Reference excerpt

Sparrenberg Castle, also known as the Sparrenburg (German: Burg und Festung Sparrenberg or Sparrenburg), is a restored fortress in the Bielefeld-Mitte district of Bielefeld, Germany. It is situated on the Sparrenberg hill (180 metres (590 ft) altitude) in the Teutoburg Forest and towers 60 metres (200 ft) above the city centre. Its current appearance mainly originated in the 16th and 19th century. The Hermannsweg, a long-distance hiking trail, passes through its grounds, directly in front of the castle. The Sparrenburg is considered to be the signature landmark of Bielefeld.

History

First centuries

The Sparrenburg was erected as a castle sometime before 1250 by the counts of Ravensberg. It guarded the Bielefeld Pass over the Teutoburg Forest, as well as acting as the ruling seat of the counts of Ravensberg, and as protection for the city of Bielefeld, probably founded around 1200. Because the construction of a protective castle generally predates the foundation of a town, it is assumed that there was an older castle. In 1256, the castle was first mentioned in records. In 1346, Bernard, Count of Ravensberg died without issue and, with his death, the line of Calvelage-Ravensberg was extinguished. The castle was transferred through marriage to Count Gerhard I of Jülich-Berg, who had been married to Bernard's niece Margaret since 1338, and its function as the ruling seat was lost. On 18 November 1377, Emperor Charles IV stayed overnight at the castle. From 1410 to 1428 the Sparrenburg served as a ruling seat for a last time, for Count William II of Ravensberg, who came from the line of the House of Jülich that ruled the Duchy of Berg. In 1511, the Sparrenburg changed hands again. William IV, Duke of Jülich-Berg, who was also the count of Ravensberg, died and County and castle were handed over to his son-in-law John III, Duke of Cleves.

Reconstruction as a fortress

Following the discovery of gunpowder and the resultant increasing use of cannon and other firearms, the new counts of Ravensberg and the owners of the Sparrenburg, the dukes of Cleves, ordered the expansion of the castle into a fortress of the Early Modern Period that could withstand bombardment from siege guns and also employ its own cannon. Around 1530, a round bastion was added in the west, only accessible from the castle itself via a bridge, from which one could control Bielefeld Pass with artillery. After some preliminary work starting in 1535, from 1556 on the Italian fortress master builder Alessandro Pasqualini and his son managed the reconstruction, which was finished in 1578 and created the largest fortress in Westphalia. The old castle was now surrounded by a terrace and a high defensive wall. In addition to the original western bastion, the Mühlenrondell, the other three corners of the fortress received round bastions and the Mühlenrondell was expanded into a pointed bastion, called "Scherpentiner, in order to further improve control over the Pass. The description Scherpentiner can only be verified at the Sparrenburg, its origin can be traced back to the Serpentinen (Serpentin = Italian for snake; German Feldschlange, culverin), which are light artillery guns of the 15th and 16th century.

Practical tests In 1609 John William von Jülich-Cleves-Berg, the last duke of Jülich died without male descendants. The collective government, arranged in 1609 by the main heirs John Sigismund, Elector of Brandenburg and duke Wolfgang Wilhelm, Count Palatine of Neuburg failed and culminated in the War of the Jülich Succession. In 1612, the castle was damaged by an earthquake. Due to the Treaty of Xanten, signed in 1614, which ended the succession conflict, the castle was handed over to Brandenburg-Prussia, which immediately granted the right of occupation to its Dutch confederates. The Dutch occupation became effective in November 1615. Years of conflict had subject the castle to war, bandits and arson. In 1623, in the course of the Thirty Years' War, which broke out in 1618, the Dutch had to retreat before the overpowering advance of the Spanish, led by count John III von Rietberg. In 1625, Brandenburg's colonel Gent unsuccessfully attempted to reconquer the Sparrenburg with the help of Ravensberg's peasants. In 1636 the Swedes and Hessians besieged the Spanish for nearly one year before they had to hand over the fortress in 1637. In 1642, they left Sparrenburg to their French allies. In 1648, the Peace of Westphalia confirmed the affiliation to Brandenburg-Prussia. In the following years the Grand Elector Frederick William stayed several times at the fortress, and two of his children were born there. During the Franco-Dutch War the Sparrenburg successfully resisted its last sieges, in 1673 against troops of Münster and in 1679 French troops.

Decline and romantic renovation At the end of the 17th century, the Sparrenburg no longer met the military requirements. Therefore, it was partly used as a prison, and partly subjected to decline. The outer walls were torn down by agreement of King Frederick II of Prussia and were used for the construction of the barracks 55, which still stands at the Hans-Sachs-Straße. In the course of the castle romanticism of the 19th century, the "Comité zur Wiederherstellung des Thurmes auf dem Sparrenberg" (Committee for the Renovation of the Tower on the Sparrenberg) was founded in Bielefeld, and it reconstructed the tower in 1842/43. In 1879, the city of Bielefeld was able to buy the complex from Prussia for a sum of 8,934.90 Marks, although the original value was assessed 70,000.00 Marks. After long discussions concerning the building's design the construction of the new great hall building was started in 1886 using building plans of the architect E. Hillebrand. On April 24, 1888, the gothic building with ballroom, restaurant, and museum rooms was opened. In 1900, a monument of the Grand Elector Frederick William, made by Fritz Schaper, was erected in the courtyard while Emperor William II, who is the nominal last count of Ravensberg, was present.

Worked examples

Example 1 — a first encounter with Sparrenberg Castle

Start with the simplest possible case. Write down what Sparrenberg 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 Sparrenberg 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 Sparrenberg 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 Sparrenberg Castle

In research
Sparrenberg 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 Sparrenberg 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
Sparrenberg Castle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1578, Buildings and structures completed in the 13th century, Buildings and structures in Bielefeld, so understanding it makes those chapters shorter.
In everyday life
Look for Sparrenberg 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.
