Burg Eltz, near the Mosel River Germany.  Of more than 500 castles in the Rhineland Palatinate region this is one of only three to have survived the many wars and destruction in the region mostly intact since the 11th century.  The Eltz family occupied the castle in the 12th century, and then continued to make renovations and additions for centuries afterwards. For this reason it wasn’t fully completed until between 1490 and 1540.  The 80-room castle is still occupied today, and looks much as it would have hundreds of years ago.  The castle is one of the few in the area that survived the Thirty Years’ War.  The French did not destroy the castle thanks to its location, and some skilled diplomacy on the part of the landowners.

It is a good walk to get to, up and down a number of hills and forest tracks through a beautiful area and a breathtaking view of the castle.  Burg Eltz is one of the hundreds of castles examined by the author while researching material for the book "Siegecraft".  Burg Eltz is, in this author's opinion, the most interesting of them all.

Pfalzgrafenstein Castle (Burg Pfalzgrafenstein) is a toll castle on Falkenau island, otherwise known as Pfalz Island in the Rhine River near Kaub, Germany.  Known as "the Pfalz," this former stronghold is famous for its picturesque and unique setting.  

The keep of this island castle, a pentagonal tower with its point upstream, was erected 1326 to 1327 by King Ludwig the Bavarian.  Around the tower, a defensive hexagonal wall was built between 1338 to 1340.  In 1477 Pfalzgrafenstein was passed as deposit to the Count of Katzenelnbogen.  Later additions were made in 1607 and 1755, consisting of corner turrets, the gun bastion pointing upstream, and the characteristic baroque tower cap.

The castle functioned as a toll-collecting station that was not to be ignored.  It worked in concert with Gutenfels Castle and the fortified town of Kaub on the right side of the river.  Due to a dangerous cataract on the river's left, about a kilometer upstream, every vessel would have to use the fairway nearer to the right bank, thus floating downstream between the mighty fortress on the vessel's left and the town and castle on its right.  A chain across the river drawn between those two fortifications forced ships to submit, and uncooperative traders could be kept in the dungeon until a ransom was delivered.  The dungeon was a wooden float in the well.

Unlike the vast majority of Rhine castles, "the Pfalz" was never conquered or destroyed, withstanding not only wars, but also the natural onslaughts of ice and floods by the river.  Its Spartan quarters held about twenty men.

Berwartstein Castle (Burg Berwartstein) was one of the most interesting castles that I have a clear memory of my parents taking us to visit on 27 March 1960.  It stands on a rocky mount in southwestern Germany, and was one of the rcok castles that were part of defences of the Palatinate during the Middle Ages.  First documented in 1152, Berwarstein is one of three significant  examples of rock castles in the region with the other two being Drachenfels and Altdahn.  They are most notable because their stairs, passages and rooms are carved out of the living rock to form part of the accommodation essential to the defence of the castle.  Although Berwartstein Castle appears more complete when compared to the ruins of neighbouring castles, it is only a restoration of the original rock castle.  It is the only castle in the Palatinate that was rebuilt and re-inhabited after its demolition.

Rock cut passageways leading under Berwartstein.  Carved out of the cliff and accessible even today are corridors and passageways which used to be part of the large underground defence network. Although not accessible today, there was once a tunnel from the castle to the village below.  These tunnels were hewn out with hammer and chisel and partly dug through the soil.  

One memory I have from those days, is that the guide took a group of us through an underground tunnel that wound some distance from the entrance to the interior storage chamber.  The guide was the only one with a flashlight, so we all joined hands in a chain link to go through the dark path (cobwebs and all).  On reaching the other end we came into a room dubbed "casemate II", with a central pillar holding up the ceiling - it had been carved out of the living rock!

Casemate II, as it appeared when we came out of the tunnel - quite the introduction to castle tunnel spelunking!

I remember my father explaining that the robber knights operating from this castle created a problem for the rulers in the area, so they commissioned one of their best knights to go and sort them out.  He managed to get the best of them, but on reflection decided they had a pretty good scheme going, and so he joined them, taking over the business, so to speak.  Even more remarkable, the fortress was so well defended, the Robber Knight died of old age, quite rare for the profession.  I am going to include some details of this castle, much of which is typical of the many I have explored during our time in Germany (1959-1963, 1979 (tour), 1981-1983, 1986 (en route to Cyprus), 1989-1992, and several tours in 2005, 2008 and 2016.

Armour and stone catapult/cannon balls.  At the age of eight, these were the first I had seen.  I have certainly view a lot more since ;o) 

During the 13th century, feudal tenants, who carried the name "von Berwartstein" inhabited the castle, which they used as a base for raids in the manner of robber barons.  The imperial cities of Strasbourg and Hagenau joined forces against the von Berwartsteins.  Following several weeks of futile attacks against the castle, they succeeded in taking it in 1314, with the help of a traitor.  A large amount of booty and about 30 prisoners were taken to Strasbourg.  The knights of Berwartstein were permitted to buy the prisoners back for a large ransom.  The knights of Berwartstein were forced to sell their castle to the brothers Ort and Ulrich von Weingarten.  Four years later the castle became the property of  Weissenburg Abbey.

The monastery at Weissenburg placed the castle in stewardship and established a feudal system.  This allowed for the dismissal of vassals who became too presumptuous.  Thus the monastery held possession of the castle for some time.  This could have continued indefinitely had the last steward of the castle (Erhard Wyler) not gone too far.  When he began feuding with the knights of Drachenfels, the Elector of the Palatinate took the opportunity to bring the Berwartstein Castle under his control.

Because of his dynastic ambitions, the Elector of the Palatinate wanted to bring all of the Weissenburg estate under his control. To accomplish this, in 1480 he ordered the knight, Hans von Trotha, who was Marshal and Commander in Chief of the Palatinate forces, to acquire to Berwartstein. In this way he could enlarge the property at a cost to the Monastery of Weissenburg. For the quarrelsome knight this was a pleasure to fulfil, since this gave him a chance to take personal revenge on the Abbot of Weissenburg. Years before, Abbot Heinrich von Homburg had imposed a church fine on his brother, Bishop Thilo.  As a starting point for this conquering expedition, this experienced warrior first renovated the castle to improve its appearance. He built strong ramparts and bastions as well as the outwork and tower called Little France castle.

After von Trotha's death, Berwartstein Castle was inherited by his son Christoph and, when he died, it went to his son-in-law, Friedrich von Fleckenstein and remained in the hands of this family for three generations.  During this time, the castle was destroyed by fire in 1591, and, since there is no mention of any attacks, it is presumed that the castle was hit by lightning.  Even though the main sections of the castle were not destroyed by the fire, it stood empty and unused for many years.  In the Peace of Westphalia (1648), Berwartstein received special mention, when it was granted to Baron Gerhard von Waldenburg, known as Schenkern, a favorite of Emperor Ferdinand III.  Since he did not restore the castle, it fell into ruins.

A certain Captain Bagienski purchased the castle in 1893.  In 1922, it was sold to Aksel Faber of Copenhagen, and thus went into foreign ownership.  Since he was seldom in Germany, he asked Alfons Wadlé to be his steward. Later Wadlé he was able to purchase the castle.  

The village of Erlenbach below the castle was completely destroyed during the Second World War, and its inhabitants sought shelter in the castle.  After the war, the roof had gone as well as the woodwork around windows, doors, staircases and other furnishings.  Since the castle was not financially supported, Alfons Wadlé went about the renovation himself.  At first he was only able to do what was essential to protect the castle from the elements.

Berwartstein has an opening on the southeast side of the cliff, commonly referred to as Aufstiegskamin ("entrance chimney").  During the early years of the castle only the rooms and casemates in the upper cliff were complete and the shaft was the only entrance to the castle.  To make it easier to ascend the shaft, a portable wooden staircase or rope ladder was placed into the castle.  In the event of attack, the staircase or ladder was hoisted up into the castle.  This enabled the entrance to be defended by just one man who was supplied with boiling sap, oil or liquid to pour on any intruder attempting to ascend the shaft.  This limited access to the castles inner rooms was probably the main reason it was never conquered during the Middle Ages.  The narrow, almost vertical cliff on which the castle stands, rises to a height of approximately 45 metres.

The extremely deep well is one of the castle builders' greatest accomplishments.  The well has a diameter of 2 metres (6 ft) and was hacked out of the rock to the bottom of the valley some 104 metres (341 feet) below.  This was essential to the castle's survival when under siege. 

The historic Great Hall or Rittersaal has a cross-vaulted ceiling. An engraving on the supporting central pillar shows that it dates to the 13th century. The south wall of the hall is made from rock and includes a hewn-out lift shaft used by the knights of Berwartstein to deliver supplies to the table and deliver food and drink from the kitchen above.

To the south on the opposite side of the valley from the castle on a spur of the Nestelberg can still be seen the tower of Little France.  This tower was part of an outwork or small subsidiary castle built by the well known knight and castellan of the Berwartstein, Hans von Trotha.  The tower was an important observation post and defensive position, and meant that any attackers would have found themselves caught in a crossfire between the tower and the castle.  The open ground in the valley below between the tower and castle still bears the name Leichenfeld (Corpse Field), a reference to the battles fought here.  There is also evidence of an underground passage between the tower and castle which is no longer accessible today since it has largely collapsed.

Nuremberg Castle with a view of the Palas, Imperial Chapel, Heathens' Tower on the left, Sinwell Tower in the middle left, the Pentagonal Tower, the Imperial Stables and Luginsland Tower on the right.  In the Middle Ages, German Kings, (respectively Holy Roman Emperors after their coronation by the Pope) did not have a capital, but travelled from one of their castles (Kaiserpfalz or Imperial castle) to the next.  For this reason, the castle at Nürnberg became an important imperial castle, and in the following centuries, all German kings and emperors stayed at the castle, most of whom did so on several occasions.  Nuremberg Castle is comprised of three sections: the Imperial castle (Kaiserburg), the former Burgraves' castle (Burggrafenburg), and the buildings erected by the Imperial City at the eastern site (Reichsstädtische Bauten).

The first fortified buildings appear to have been erected around 1000.  Thereafter, three major construction periods may be distinguished:

  • the castle built under the Salian kings respectively Holy Roman Emperors (1027–1125);
  • a new castle built under the Hohenstaufen emperors (1138–1254);
  • reconstruction of the Palas as well as various modifications and additions in the late medieval centuries.

The castle lost its importance after the Thirty Year's War (1618 to 1648). In the 19th century with its general interest in the medieval period, some modifications were added.  During the Nazi period, in preparation of the Nuremberg party rally in 1936, it was "returned to its original state."  A few years later, during the Second World War and its air raids in 1944/1945, a large part of the castle was laid in ruins.  It took some thirty years to complete the rebuilding and restoration to its present state.

Wartburg Castle, overlooking the town of Eisenach in the state of Thuringia, Germany, 27 May 2016.  Originally built in Middle Ages, The Wartburg stands on a cliff rising 410 meters (1,350 ft) to the southwest of and overlooking the town of Eisenach, in the state of Thuringia, Germany.  It was the home of St. Elisabeth of Hungary, the place where Martin Luther translated the New Testament of the Bible into German, the site of the Wartburg festival of 1817 and the supposed setting for the possibly legendary Sängerkrieg.  It was an important inspiration for Ludwig II when he decided to build Neuschwanstein Castle.  The Wartburg castle contains substantial original structures from the 12th through 15th centuries, but much of the interior dates back only to the 19th century.

The castle's foundation was laid about 1067 by the Thuringian count of Schauenburg, Ludwig der Springer, a relative of the Counts of Rieneck in Franconia.  Together with its larger sister castle Neuenburg in the present-day town of Freyburg, the Wartburg secured the extreme borders of his traditional territories.  Ludwig der Spring is said to have had clay from his lands transported to the top of the hill, which was not quite within his lands, so he might swear that the castle was built on his soil.

The castle was first mentioned in a written document in 1080 by Bruno, Bishop of Merseburg, in his De Bello Saxonico ("The Saxon War") as Wartberg.  During the Investiture Controversy, Ludwig's henchmen attacked a military contingent of King Henry IV of Germany.  The count remained a fierce opponent of the Salian rulers, and upon the extinction of the line, his son Louis I was elevated to the rank of a Landgrave in Thuringia by the new German king Lothair of Supplinburg in 1131.

From 1172 to 1211, the Wartburg was one of the most important princes' courts in the German Reich.  Hermann I supported poets like Walther von der Vogelweide and Wolfram von Eschenbach who wrote part of his Parzival here in 1203.

The castle thus became the setting for the legendary Sängerkrieg, or Minstrels' Contest in which such Minnesänger as Walther von der Vogelweide, Wolfram von Eschenbach, Albrecht von Halberstadt (the translator of Ovid) and many others supposedly took part in 1206/1207.  The legend of this event was later used by Richard Wagner in his opera Tannhäuser.

At the age of four, St. Elisabeth of Hungary was sent by her mother to the Wartburg to be raised to become consort of Landgrave Ludwig IV of Thuringia.  From 1211 to 1228, she lived in the castle and was renowned for her charitable work.  In 1221, Elisabeth married Ludwig.  In 1227, Ludwig died on the Crusade and she followed her confessor Father Konrad to Marburg.  Elisabeth died there in 1231 at the age of 24 and was canonized as a saint of the Roman Catholic Church, just five years after her death.

In 1247, Heinrich Raspe, the last landgrave of Thuringia of his line and an anti-king of Germany, died at the Wartburg.  He was succeeded by Henry III, Margrave of Meissen.

In 1320, substantial reconstruction work was done after the castle had been damaged in a fire caused by lightning in 1317 or 1318.  A chapel was added to the Palas.  The Wartburg remained the seat of the Thuringian landgraves until 1440.  From May 1521 to March 1522, Martin Luther stayed at the castle under the name of Junker Jörg (the Knight George), after he had been taken there for his safety at the request of Frederick the Wise following his excommunication by Pope Leo X and his refusal to recant at the Diet of Worms.  It was during this period that Luther translated the New Testament from ancient Greek into German in just ten weeks.  Luther's work was not the first German translation of the Bible but it quickly became the most well known and most widely circulated.

From 1540 until his death in 1548, Fritz Erbe, an Anabaptist farmer from Herda, was held captive in the dungeon of the south tower, because he refused to abjure anabaptism.  After his death, he was buried in the Wartburg near the chapel of St. Elisabeth.  In 1925, a handwritten signature of Fritz Erbe was found on the prison wall.  Over the next few centuries, the castle fell increasingly into disuse and disrepair, especially after the end of the Thirty Years' War when it had served as a refuge for the ruling family.  In 1777, Johann Wolfgang von Goethe stayed at the Wartburg for five weeks, making various drawings of the buildings.

On 18 October 1817, the first Wartburg festival took place.  About 500 students, members of the newly founded German Burschenschaften (fraternities), came together at the castle to celebrate the German victory over Napoleon four years before and the 300th anniversary of the Reformation, condemn conservatism and call for German unity under the motto "Honour - Freedom - Fatherland".  Speakers at the event included Heinrich Hermann Riemann, a veteran of the Lützow Free Corps, the philosophy student Ludwig Rödiger, and Hans Ferdinand Massmann.  This event and a similar gathering at Wartburg during the Revolutions of 1848 are considered seminal moments in the movement for German unification.

During the rule of the House of Saxe-Weimar-Eisenach, Grand Duke Karl Alexander ordered the reconstruction of Wartburg in 1838.  The lead architect was Hugo von Ritgen, for whom it became a life's work.  In fact, it was finished only a year after his death in 1889.  Drawing on a suggestion by Goethe that the Wartburg would serve well as a museum, Maria Pavlovna and her son Karl Alexander also founded the art collection (Kunstkammer) that became the nucleus of today's museum.  The reign of the House of Saxe-Weimar-Eisenach ended in the German Revolution in 1918.  In 1922, the Wartburg Stiftung (Wartburg Foundation) was established to ensure the castle's maintenance.

After the end of the Second World War, Soviet occupation forces took the renowned collection of weapons and armour.  Its whereabouts still remain unknown.  The Rüstkammer (armoury) of the Wartburg once contained a notable collection of about 800 pieces, from the splendid armour of King Henry II of France, to the items of Frederick the Wise, Pope Julius II and Bernhard von Weimar.  All these objects were taken by the Soviet Occupation Army in 1946 and have disappeared in Russia.  Two helmets, two swords, a prince's and a boy's armour, however, were found in a temporary store at the time and a few pieces were given back by the USSR in the 1960s.  The new Russian Government has been petitioned to help locate the missing treasures.

Under communist rule during the time of the GDR extensive reconstruction took place in 1952-54.  In particular, much of the palas was restored to its original Romanesque style.  A new stairway was erected next to the palas.  In 1967, the castle was the site of celebrations of the GDR's national jubilee, the 900th anniversary of the Wartburg's foundation, the 450th anniversary of the beginning of Luther's Reformation and the 150th anniversary of the Wartburg Festival.  In 1983, it was the central point of the celebrations on account of the 500th birthday of Martin Luther.

The largest structure of the Wartburg is the Palas, originally built in late Romanesque style between 1157 and 1170.  It is considered the best-preserved non-ecclesial Romanesque building north of the Alps.  (Wikipedia)

Schloss Hohenzollern, is the ancestral seat of the imperial House of Hohenzollern. It is the third of three castles built on the site, and is located on top of Mount Hohenzollern, above and south of the town of Hechingen, on the edge of the Swabian Jura of central Baden-Würtemberg, Germany.  

The first castle on the mountain was constructed in the early 11th century.  Over the years the House of Hohenzollern split several times, but the castle remained with the branch of the family, that later acquired its own imperial throne.  This castle was completely destroyed in 1423 after a ten-month siege by the free imperial cities of Swabia.

The second castle, a larger and sturdier structure, was constructed from 1454 to 1461, which served as a refuge for the Catholic Swabian Hohenzollerns, including during the Thirty Year's War.  By the end of the 18th century it was thought to have lost its strategic importance and gradually fell into disrepair, leading to the demolition of several dilapidated buildings.

The third, and current, castle was built between 1846 and 1867 as a family memorial by Hohenzollern King Frederick William IV of Prussia.  No member of the Hohenzollern family was in permanent or regular residence when it was completed, and none of the three German Emperors of the late 19th and early 20th century German Empire occupied the castle; in 1945 it briefly became the home of the former Crown Prince Wilhelm of Germany, son of the last Hohenzollern monarch, Kaiser Wilhelm II.

Trifels Castle, Anweiler, Germany.  First mentioned in documents dated 1081, this castle was designated as a secure site for preserving the Imperial Regalia of the Hohenstaufen Emperors until they were moved to Walburg Caste in Swabia in 1220.  Richard the Lionheart, King of England was kept a prisoner here, after he was captured by Duke Leopold V of Austria near Vienna in Dec 1192 as he was returning from the Third Crusade.  He was handed over to Emperor Henry VI of Hohenstaufen and his period of captivity from 31 March to 19 April 1193 is well documented.  Our family visited this castle often during our postings to Germany.  Its a steep climb. 

Schloßß Trifels, where Richard the Lionheart had been held prisoner, was one of many castles our family visited over the years, and in fact, it was the very first for me on Saturday, 27 June 1959 Saturday.

Marksburg, seen here from the western riverside of the Rhine, is a fortress above the town of Braubach in Rhineland-Palatinate, Germany.  It is located on a schist rock iat a height of 160 metres (525 feet).  It is the only medieval castle of the Middle Rhine that has never been destroyed.  Since 2002, the castle is one of the principal sites of the UNESCO World Heritage Rhine Gorge.  The Marksburg Castle is one of the three with its original elements intact from the 11th century.  It has an extensive collection of medieval artifacts, and is the repository of castle museum books and documents for most of Germany. 

I felt that this specific castle would make a good cover for a book about sieges.

Burg Hohengeroldseck.  Most Canadians who lived in Lahr, Germany, home of Canadian Forces Europe Headquarters and 4 Canadian Mechanized Brigade Group (4 CMBG) until 1993, will be familiar with the 12th century castle nearby named Hohengeroldseck, and a secondary castle overlooking it, Schloss Lutzelhardt.

 (Lahr Historical Society Photo)

Burg Hohengeroldseck as it appeared before its destruction in the 1600s.  The castle was built ca 1270 on the Seelbacher Schönberg mountain between Schutter and Kinzigtal in the Ortenau, not far from Offenburg and Lahr.  At that time, it served as the family seat of the Lords of Geroldseck, initially under Walther I von Geroldseck.  (Hohengeroldseck was a state of the Holy Roman Empire).  In 1486 the castle came into the hands of the Elector Philipp von der Pfalz.  In 1534, it passed back into the hands of the Geroldseck family, when brothers Walter and Gangolf II von Geroldseck received it as a fief.  The Geroldseckers died out in 1634, and in 1635, the castle was received by Count Otto Adolf von Kronberg as an Austrian fief.  The castle was extensively destroyed by French soldiers in 1689.  In 1697, plans were made to convert the ruins into a Habsburg fortress, but the idea was abandoned.  From 1711 the Austrians controlled the Geroldsecker area by force.  In 1891, work was begun to repair and save elements of the ruin.  Additional repairs were conducted on the ruin between 1958 and 1963.  The Association for the Preservation of the Ruins of the Geroldseck eV is presently engaged in preserving the ruins of the castle, as well as funding new excavations and repairs.

Marienberg Fortress (Festung Marienberg) is a prominent landmark on the left bank of the Main river in Würzburg, in the Franconia region of Bavaria, Germany.  The mighty Fortress Marienberg is a symbol of Würzburg and served as a home of the local prince-bishops for nearly five centuries.  It has been a fort since ancient times.  Most of the current structures originally were built in Renaissance and Baroque styles between the 16th and 18th centuries.  After Gustavus Adolphus of Sweden conquered the area in 1631 during the Thirty Year's War, the castle was reconstructed as a Baroque residence.  After it ceased to serve as residence of the Bishops of Würzburg, the fortress saw repeated action in the wars of the late 18th and 19th centuries.  Festung Marienberg was severely damaged by British bombs in March 1945 and only fully rebuilt in 1990.  Today, it houses two museums.

Chateau-de-Gisors, Eure, Normandy, France.  The castle was a key fortress of the Dukes of Normandy in the 11th and 12th centuries.  It was intended to defend the Anglo-Norman Vexin territory from the pretensions of the King of France.  In 1193, while King Richard I of Enlgand (also Duke of Normandy) was imprisoned in Germany, the castle fell into the hands of King Philip II of France.  After Richard's death in 1199, Philip conquered much of the rest of Normandy and Gisors thereafter lost a good part of its importance as a frontier castle.  The castle is also known for its links with the Templars.  Put into their charge by the French king between 1158 and 1160, it became the final prison of the Grand Master of the Order, Jacques de Molay, in 1314.  Although it has been estimated that the bailey could have housed 1,000 soldiers, in 1438 (during the Hundred Years' War) the English garrison numbered just 90.  By 1448, this had decreased to 43.

The first building work is dated to about 1095, and consisted of a motte, which was enclosed in a spacious courtyard or bailey.  Henry I of England, Duke of Normandy, added an octagonal stone keep to the motte.  After 1161, important reinforcement work saw this keep raised and augmented; the wooden palisade of the motte converted to stone, thus forming a chemise; and the outer wall of the bailey was completed in stone with flanking towers. The octagonal keep is considered one of the best preserved examples of a shell keep.  A second keep, cylindrical in shape, called the Prisoner's Tower (tour du prisonnier), was added to the outer wall of the castle at the start of the 13th century, following the French conquest of Normandy.  Further reinforcement was added during the Hundred Years' War.  In the 16th century, earthen ramparts were built.

If you would like to learn more about castles and sieges have a look here:

It has been said that the taking of a fortress depends primarily on the making of a good plan to take it, and the proper implementation and application of the resources to make the plan work. Long before a fortress has been besieged and conquered, it has to have been outthought before it can be outfought. This book outlines some of the more successfully thought out sieges, and demonstrates why it is that no fortress is impregnable.

A siege can be described as an assault on an opposing force attempting to defend itself from behind a position of some strength. Whenever the pendulum of technology swings against the "status quo," the defenders of a fortification have usually been compelled to surrender. We must stay ahead of the pendulum, and not be out-thought long before we are out-fought, for, as it will be shown in this book, "no fortress is impregnable."
