Lucera Castle

Lucera 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 Lucera Castle rather than just read about it. In short: The castle of Lucera is a castle located in the municipality of Lucera, in the province of Foggia, southern Italy, dating back to the 13th century. Currently only remnants of the castle and its walls are left.

Key takeaways

Lucera 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 Lucera Castle to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lucera Castle from memory before moving on to harder problems.

Reference excerpt

The castle of Lucera is a castle located in the municipality of Lucera, in the province of Foggia, southern Italy, dating back to the 13th century. Currently only remnants of the castle and its walls are left.

History The construction of the castle was commissioned by Frederick II, Holy Roman Emperor following his decision to relocate the Saracen rebels of Sicily in the town of Lucera. The castle was built in 1233 on the foundations of a Roman citadel and the walls were added later (between 1269 and 1283) by Charles I of Anjou. This addition was necessary for the difference in use that he wanted to make of the structure: from imperial palace as was intended to fortified castle and permanent military garrison. The material of construction was mainly acquired from the remains of Roman buildings still present in the area. The castle, in fact, lies in the same place of the acropolis of the ancient Roman city. The complex was heavily damaged by an earthquake that struck the area in 1456, and was almost completely demolished in the 18th century to use the resulting material for the construction of the court. This ended in the 19th century, when the first restoration works begun.

Structure

The square truncated pyramidal base, still visible, comes from following French projects. The Hohenstaufen castle, of which there are only buried fragments, was inside this tower, an outward complex that rose three floors. The castle was built around a central square courtyard. The courtyard at the third floor instead presented an octagonal shape, characteristics that resemble very closely the most famous structure built by Frederick II in the area: Castel del Monte. The Swabian castle had a normal entry at street level. The surrounding French base has no access to the street level, so was raised the question of how it was possible to access it. It has been assumed that the entry was made possible by the presence of ladders downed from above, while the most evocative hypothesis (supported by the discovery of tunnels near the castle) suggests the access from an underground entrance. The absence of a doorway, however, is significant of the strategic importance of the castle, which in this way was more difficult to conquer. A circular 14-meter-deep cistern located under the courtyard guaranteed the water to the castle. The irregular wall that surrounds the entire hill on which stands the castle is 900 meters long, and also consists of 13 square towers, two pentagonal bastions, 7 buttresses and two cylindrical corner towers. The latter - with regular section of great precision - were with certainty part of the Frederick's project for Lucera. Even access to these walls - with the bridge over the big dig - reminds the Swabian castles in the homeland of the Emperor, such as the castle of Wildenstein, which has a similar entry.

Worked examples

Example 1 — a first encounter with Lucera Castle

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

In research: Lucera 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 Lucera 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: Lucera Castle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1233, Buildings and structures in the Province of Foggia, Castles in Apulia, so understanding it makes those chapters shorter.
In everyday life: Look for Lucera 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.
