Forteresse de Salses was built between 1497 and 1504, at the order of Ferdinand II of Aragon. It was designed by engineer Francisco Ramiro Lopez, the king’s commander and artillery master, to block access to France from Roussillon. It was originally destined to replace a previous château, from which the town takes its name (Salses-le-Château). The earliest records of this château, situated on a neighbouring rocky outcrop, date back to 1007, and it was destroyed during a siege in 1496.
The Fortress of Salses is a masterpiece of military architecture, designed to protect against the recently developed metal cannonball. It is a prime example of the transition between the mediaeval château, with its keep and cylindrical towers with long curtain walls, and the modern fortress, with its rigorously geometric and part-buried structure. Its walls are around 10 metres thick, and the fortress is divided over seven levels served by a maze of corridors and multiple interior defensive chicanes. By virtue of the defensive plan, the fortress is divided into three entirely independent sections.
The entire system was strengthened by a vast dry moat and buffer zone and, to the east, south and north-west, by three separate, pointed towers that acted as additional, advance defensive posts.
The fortress’ location was selected because of the abundant local springs that would be useful during times of siege. It occupies a strategically important position on the main route between France and Spain, on a narrow strip of land between the Corbières mountains and the marshland bordering the lakes.
The fortress, which survived a fire in 1503 despite being unfinished, was the subject of multiple attacks by both the French and Spanish. It was besieged, changed hands in 1503, 1639 and 1640, and was finally conquered by the French in 1642 following a fourth siege. With the signature of the Treaty of the Pyrenees on November 16th, 1659, the fortress’ destiny was finally sealed, and it became the permanent property of France.
Given its distance from the border, the fortress subsequently lost its strategic importance and was threatened with demolition on several occasions because it was becoming too expensive to maintain. The fortress nevertheless survived and was repaired and transformed from 1691 onwards, under the supervision of Vauban.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.
