The Castle of Lanjarón, locally known as the Moorish Castle, is a small medieval fortress located a quarter mile from the village. It is dominating on a rocky outcrop, the valley of the Lanjarón River, next to the Salado canyon. It is formed by two enclosures with some small sections of the outer wall. Signs of a tower are preserved; a bastion square, masonry at its bottom and above a adobe. At the south of the complex is an underground cistern, covered with a vault of brickwork.
Lanjarón castle was built between the 13th and 16th centuries in the late Moorish age and restored by Christians later.
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.
