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:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
