Reference excerpt

Pfalzgrafenstein Castle (German: Burg Pfalzgrafenstein), also known as the Pfalz, is a toll castle situated on Falkenau island in the Rhine River, adjacent to Kaub, Germany. First established in 1326/27 by King Ludwig IV the Bavarian, the castle served to collect river tolls from passing traffic. Also seeing military activity, it withstood a 39 day siege in 1504 in the War of the Succession of Landshut and was occupied by Spanish forces for 11 years from 1620 in the Thirty Year's War. The castle has undergone various modifications since its original construction, most notably modernising fortifications in 1607 and the addition of a baroque tower cap in 1714. Pfalzgrafenstein Castle was used as a key point for the crossing of the Rhine in 1814 by Russo-Prussian forces during the campaign against Napoleon. Toll collection ceased in 1867, but the castle has remained in good condition and is now preserved as a public museum.

Description The central pentagonal tower of Pfalzgrafenstein Castle is 36 metres high, with 6 storeys. The 25 metre high outer wall gives the castle a footprint of 51 x 21 meters. The wall is 2.60 meters thick and includes two battlements. Today preserved as a public museum, the interior contains furniture from the 17th to 19th centuries and household items made of clay and tin. There is a 17th century pizza oven on the second floor. The castle entrance has a wooden portcullis sheathed in iron set against the inner wall. French writer Victor Hugo described the castle as "a stone ship, eternally floating on the Rhine, eternally anchored before the Palatinate town". The area is part of the Rhine Gorge, which was added to the UNESCO list of World Heritage Sites in June 2002.

History

Construction and early history The original central tower of Pfalzgrafenstein Castle was built in 1326/27 by King Ludwig (Louis IV) of Bavaria to increase his toll revenue. Today the tower is 36 metres high and has 6 storeys. Since it stood alone, it was built pentagonally as a wave- and ice-breaker. In reaction, Pope John XXII incited his bishops of Mainz, Trier and Cologne to excommunicate Ludwig, as they were concerned that his construction threatened to undermine their own nearby toll collections at the Mouse Tower at Bingen and at Stolzenfels Castle, near Koblenz. Pope John XXII had already attempted to excommunicate Ludwig in 1325 because of his toll collection at Gutenfels Castle, however this address remained inactive. In c. 1340, it was likely this dispute with the church that caused Ludwig to build a six-sided turreted wall around the tower, 12 metres high, to improve its defence and to serve as a better ice-breaker. Pope John XXII three times requested his bishops of Mainz, Trier and Cologne to take action against the toll at Kaub, but nothing was done. To ensure tolls were paid, chain booms were raised across the narrow river passage near the castle. If the toll was paid, the chain would be lowered and the ship could pass, or else the ship would be seized and the crew imprisoned in the castle dungeon. Passing ships could not use the wider channel on the other side of the castle due to a treacherous stretch of water downstream. The castle dungeon was a wooden raft at the bottom of a well. Prisoners were lowered by rope and would remain there until a ransom was paid. Tolls were paid at a customs house in Kaub as ships could not dock properly on Falkenau island. In 1339, Ludwig gifted the castle to Count Rudolph II, the Elector Palatine, his nephew. According to a legal record from 1473, Pfalzgrafenstein Castle was recognised as a site where the Palatine bailiff could imprison defendants and conduct trials, including cases of capital punishment under the authority of the Elector Palatine. In 1477, Pfalzgrafenstein Castle was given as a deposit to the Count of Katzenelnbogen by Count Palatine Philip of Wittelsbach, expiring on his death. The final male descendent of the Counts of Katzenelnbogen, Philipp I, died in 1479, causing a 44 year-long inheritance dispute lasting until 1523.

Military activity and architectural additions In 1504, together with Kaub and nearby Gutenfels Castle, Pfalzgrafenstein Castle withstood a 39 day siege by Landgrave William II of Hesse in the War of the Succession of Landshut. Pfalzgrafenstein survived unscathed. The Hessians withdrew after taking considerable losses in men and artillery. Additions to Pfalzgrafenstein were made in 1607 by Elector Friedrich IV, adding the gun bastion pointing upstream, interior arcades, and completing the outer wall as it is seen today. These changes allowed modern guns to be brought into the castle much more easily. Pfalzgrafenstein was the first Middle Rhine castle to adapt to this new technology. In 1620, the castle was occupied by Spanish forces under General Spinola in the Thirty Year's War. While there was a brief exchange of gunfire at Kaub, Pfalzgrafenstein Castle was taken without a fight and the garrison permitted to freely withdraw. Hessian forces attacked Kaub and besieged Gutenfels and Pfalzgrafenstein in December 1631 with 400 men, until the Spanish capitulated in January 1632. During the War of the Spanish Succession (1701–1714), Pfalzgrafenstein Castle was used as to hold prisoners of war. The distinctive baroque tower cap of was added in 1714. The castle's current appearance is a result of a fire and subsequent renovation in 1756.

The Napoleonic period In 1793, Gutenfels Castle surrendered to French Revolutionary forces and gave up all military equipment. The French commander had the guns from Pfalzgrafenstein and Gutenfels removed. A few weeks later, after the French had left, the garrison of invalids returned to both castles. They remained there until the garrison was disbanded. The castle was relinquished by the Electoral Palatinate in 1803 to come under control of the House of Nassau, later the Duchy of Nassau following the dissolution of the Holy Roman Empire in 1806. The island of the castle was used for the crossing of the Rhine by Prussian and Russian forces under Field-Marshal von Blücher in pursuit of Napoleon, following the decisive French defeat at the Battle of Leipzig. On 1 January 1814, a pontoon bridge was constructed by Russian engineers, allowing Blücher's army of 60,000 men, 20,000 horses and 220 guns to cross. The castle had been unoccupied since the garrison of the Electoral Palatinate withdrew in 1803. The army crossed over several days.

Worked examples

Example 1 — a first encounter with Pfalzgrafenstein Castle

Start with the simplest possible case. Write down what Pfalzgrafenstein Castle claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pfalzgrafenstein Castle before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pfalzgrafenstein Castle ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pfalzgrafenstein Castle

In research
Pfalzgrafenstein Castle appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pfalzgrafenstein Castle in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pfalzgrafenstein Castle is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1340 establishments in Europe, 1340s establishments in the Holy Roman Empire, 14th-century fortifications, so understanding it makes those chapters shorter.
In everyday life
Look for Pfalzgrafenstein Castle outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
