The Castle of Capdepera is one of the largest castles on the Majorca island. Its construction began in 310, but in the fourteenth century it was rebuilt on the remains of a Muslim village.
The Castle of Capdepera is important to the island as it was from here that the surrender of Menorca, the island neighbouring Majorca in the Balearic archipelago, was accomplished. King James I of Aragon, having conquered Majorca, decided he needed his troops for the future conquest of Valencia. He devised a ploy to deceive the Muslims residing on Menorca and cause them to surrender. To do this, he ordered a large number of bonfires lit in Capdepera so that they were visible from the neighbouring island. This was to make the Saracen Menorcans believe that a large army had camped there and were preparing to invade Menorca. The ruse worked. So finally, at this very castle, James I signed the Treaty of Capdepera, through which the Menorcan Muslims were allowed to remain there in submission to the King of Aragon under tribute.
The first construction of a fortress on this site was by Romans. It was later enlarged by the Moors. It was destroyed during Christian invasions but they later constructed another structure in the same location in the fourteenth century.
King James II (1285-1295) having already founded the town of Capdepera in 1300, ordered the population of the area, which had been scattered, to build the walled enclosure surrounding one of its watchtowers now known as Miquel Nunis. Its strategic location on a hill allowed them to view the adjacent lands and sea channel separating the two islands.
The castle was occupied by military troops up to 1854 when it was abandoned. From then until 1983 it was under private ownership. At that time the owners donated it to the Capdepera Town Council. Today it remains open for tourist viewing throughout the year.
References:The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
