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 de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
