Château de Salveterra was built by Jacques I of Aragon in 1246 to the border between France and Kingdom of Aragon. It was besieged in 1598 and 1639 by French troops. In the 16th century, the village and castle were abandoned. The castle ruins remain south of the plateau today. It consists of an enclosure protected by a moat, tower, vaulted rooms and a walkway portion with battlements and loopholes.References:
The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
