Klusenstein Castle

Klusenstein Castle is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Klusenstein Castle rather than just read about it. In short: Klusenstein is a castle in Hemer, Germany, located on a 60m high cliff above the valley of the Hönne river. The castle was built in 1353 as a boundary fortification of the earldom Mark.

Key takeaways

Klusenstein Castle belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Klusenstein Castle to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Klusenstein Castle from memory before moving on to harder problems.

Reference excerpt

Klusenstein is a castle in Hemer, Germany, located on a 60m high cliff above the valley of the Hönne river. The castle was built in 1353 as a boundary fortification of the earldom Mark.

History The castle was built in 1353 by Gerhard of Plettenberg, a vassal of earl Engelbrecht III of the Mark. Levold of Northof (1279-1359?), the chronicler of earl Engelbrecht, wrote

In denseluen jair, als die vurs. Greue Engelbrecht auer Meer reysden, beghan Gerit van Plettenbrecht in afwesen des Greuen dat Slot ind Stat to nyenraide in Suderlande to tymmeren ind oick Slot ten Cluysensteyn. which translates to

In the year when Earl Engelbrecht was traveling beyond the sea, Gerit of Plettenberg in the absence of his earl began to build the castle and town of Neuenrade in the Sauerland, as well as the castle of Klusenstein. The castle formed the boundary fortification of the earldom Mark to the bishopric state of Cologne and the earldom Arnsberg. All three territories met at the Hönne river valley, the castle was also overlooking an old road crossing the valley. During the feud between earl Engelbert and Gottfried IV of Arnsberg, the castle was under siege in 1366 but did not fall. When the last Earl of Arnsberg, Gottfried IV, sold the earldom to the bishop of Cologne, the castle lost its importance. Until the 17th century, the family of Werminghausen owned the castle. During the 30 years war (1618–48) both Swedish and Hessian troops stayed in the castle. In 1695 the Brabeck family bought the castle and sold it in 1812 to the Löbbecke family. In 1904 it was sold to the Hoesch company, and now belongs to the company Rheinkalk. For the 650th anniversary in 2003 the castle and the adjoining buildings were renovated.

Etymology The origin of the name Klusenstein isn't fully known. While the second part stein simply means rock, the word Kluse may either refer to a rift in the rock, or alternatively from the dialect word for hermitage.

Location

The castle is located on a 60m high cliff over the Hönne river valley, at around the narrowest part of the valley. At the bottom of the rock is a small cave in total 51m long. One corridor bends upward, but about 30m below the plateau it is blocked by stones. There were legends about a secret escape route out of the castle, in 2003 the top entrance to the cave was found below the eastern palais destroyed in 1840. Below the castle is a mill named Klusenstein mill, though it did not belong to the castle. Since 1912 the railway connecting Balve and Menden runs directly below the castle.

Worked examples

Example 1 — a first encounter with Klusenstein Castle

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

In research: Klusenstein 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 Klusenstein 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: Klusenstein Castle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1353, Buildings and structures in Märkischer Kreis, Castles in North Rhine-Westphalia, so understanding it makes those chapters shorter.
In everyday life: Look for Klusenstein 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.
