Palazzo Re Enzo

Palazzo Re Enzo 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 Palazzo Re Enzo rather than just read about it. In short: Palazzo Re Enzo is a palace located on Piazza del Nettuno, 1 in the historic center of Bologna, northern Italy. The palace takes its name from Enzio of Sardinia, Frederick II's son, who was prisoner here from 1249 until his death in 1272.

Key takeaways

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

Reference excerpt

Palazzo Re Enzo is a palace located on Piazza del Nettuno, 1 in the historic center of Bologna, northern Italy. The palace takes its name from Enzio of Sardinia, Frederick II's son, who was prisoner here from 1249 until his death in 1272. The palace is presently used to sponsor cultural events and exhibitions.

History The palace was built between 1244 and 1246 as an extension of the nearby Palazzo del Podestà, which had proven insufficient for the exigences of the Commune of Bologna. It was therefore initially known as Palatium Novum ("New Palace"). Three years after the palace completion, Enzio was captured by the Guelphs at the Battle of Fossalta, and after a short stay in Anzola he was moved here, where he remained until his death. Enzio was allegedly left free within the palace by day, but by night he was kept into a cage hanging from the ceiling. He was also allowed to meet women: in his will he mentions three natural daughters, but a legend talks about a fourth son he had from a peasant, Lucia di Viadagola. The son was called Bentivoglio, from the words "Amore mio, ben ti voglio" that he said to his beloved (meaning "My love, I'm fond of you"), and he would be the ancestor of the Bentivoglio family, later rulers of Bologna. In 1386 Antonio di Vincenzo finished the Sala dei Trecento ("Hall of the Three-Hundred"), which was to become the city's archive. The last floor was largely renovated in 1771 by Giovanni Giacomo Dotti. The current Gothic appearance dates from the restoration of 1905 due to Alfonso Rubbiani. On the right of the palace is the access to the chapel of Santa Maria dei Carcerati, where the condemned to death went to. In the first floor was held the Carroccio and the war machines, while in the middle floor were the offices of the praetor and the chapel.

Worked examples

Example 1 — a first encounter with Palazzo Re Enzo

Start with the simplest possible case. Write down what Palazzo Re Enzo 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 Palazzo Re Enzo 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 Palazzo Re Enzo 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 Palazzo Re Enzo

In research: Palazzo Re Enzo 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 Palazzo Re Enzo 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: Palazzo Re Enzo is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1245, Gothic palaces in Italy, Houses completed in the 13th century, so understanding it makes those chapters shorter.
In everyday life: Look for Palazzo Re Enzo 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.
