Real Cittadella

Real Cittadella 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 Real Cittadella rather than just read about it. In short: The Real Cittadella was a fort in Messina, Sicily, southern Italy. The Cittadella was built between 1680 and 1686 by the Spanish Empire, and it was considered to be one of the most important fortifications in the Mediterranean.

Key takeaways

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

Reference excerpt

The Real Cittadella was a fort in Messina, Sicily, southern Italy. The Cittadella was built between 1680 and 1686 by the Spanish Empire, and it was considered to be one of the most important fortifications in the Mediterranean. Most of the fort was demolished in the 20th century, but some parts can still be seen.

History

Background and construction The Real Cittadella was built by the Spanish Empire (who controlled the Kingdom of Sicily) between 1680 and 1686. It was built to defend the port of Messina, but it was also meant to establish a strong garrison in the city to prevent the population from revolting, as had happened a few years earlier in 1674. The fort was designed by Carlos de Grunenbergh, the military engineer of the Viceroy of Sicily. It was built in the centre of the peninsula of San Raineri, and was cut off from the mainland by a moat. The extremity of the peninsula was occupied by the Forte del Santissimo Salvatore. A neighborhood populated by 8000 people, a Benedictine monastery and several churches had to be demolished to make way for the construction of the Cittadella.

18th and 19th centuries The Spanish lost control of Sicily to the House of Savoy in 1713. In 1718, they invaded the island during the War of the Quadruple Alliance, and the Cittadella surrendered to the Spanish general Spinola. A year later it was recaptured by the Austrian Count Claude Florimond de Mercy. The Cittadella was again captured by the Bourbon Charles III of Spain in 1735, during the War of the Polish Succession. The fort was also used as a prison, and the French geologist Déodat Gratet de Dolomieu was imprisoned there in 1798. During the Sicilian revolution of 1848, the rebels did not capture the Cittadella, although they succeeded in taking over Forte Gonzaga and a number of other fortifications in the city. The rebels bombarded the Cittadella, but Bourbon troops held out until a relief force arrived in September 1849 and crushed the rebellion. The Cittadella was again heavily bombarded by the Piedmontese army during the Expedition of the Thousand in 1860. It was the last stronghold of the Kingdom of the Two Sicilies on the island, and its garrison surrendered on 13 March 1861. Following the capture of the fort, the people of Messina demanded its demolition, but the new government saw its importance and the damage sustained in the sieges of 1848-49 and 1860-61 was repaired. The fort remained an active military installation until the earthquake of 1908, when it was converted into a warehouse.

Partial demolition

In the 1920s, Norimberga, San Francesco and San Carlo Bastions were demolished following the opening of a new road. The remaining parts of the fort were occupied by the military once again during World War II, and the structure was damaged by aerial bombardment. After the war, the area was industrialized. Porta Grazia, the fort's main gate, was relocated to Piazza Casa Pia dei Poveri in 1961.

Present day Today, San Stefano and San Diego Bastions, the adjoining curtain walls and some of the outworks remain intact. The foundations of the demolished bastions still exist underground, and are worthy of preservation. The remaining parts of the Cittadella are neglected, and sometimes waste is illegally dumped in the fort.

Layout The Real Cittadella was a pentagonal star fort, and was typical example of 17th century military architecture. It had five corner bastions (named Norimberga, San Francesco, San Carlo, San Stefano and San Diego), which were linked by curtain walls. A cavalier was located on each bastion. In addition, the fort had a number of outworks, including a ravelin, lunettes, counterguards and faussebrayes.

Worked examples

Example 1 — a first encounter with Real Cittadella

Start with the simplest possible case. Write down what Real Cittadella 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 Real Cittadella 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 Real Cittadella 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 Real Cittadella

In research
Real Cittadella 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 Real Cittadella 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
Real Cittadella is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1686 establishments in the Kingdom of Sicily, 1686 establishments in the Spanish Empire, Buildings and structures completed in 1686, so understanding it makes those chapters shorter.
In everyday life
Look for Real Cittadella 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.
