The first mention of the Tongelaar Castle on this site dates from 1282 when it was dedicated to Count Floris V by Jan van Cuyk. The Van Cuyk family was probably owner of the castle until somewhere in the 15th century when it was owned by the Van Merwick family. In later centuries ownership of the castle passed through several noble Dutch and Belgian families until the 20th century.
The only medieval part of Tongelaar Castle is the square brick tower. This was originally the gate tower and would have been equipped with a drawbridge. The large window would have been the entrance. This tower dates back to the early 15th century. Archeological research proved that there had been a fortified medieval building at the opposite side of the gate tower but that they had not been connected by walls with each other. The tower would have had several living quarters and had a prison below ground level.
All the other present buildings were built in the 18th and 19th century. The western wing was either built on the foundations of an earlier building or built with the use of old building materials.
The tower is now a corner tower of a closed square farm with a simple courtyard.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.
