In 1316, Guilhem de Toulouse, seneschal of Périgord for Edouard II of England, chose Molières as the base of his power. He complained that there was no fortified house to protect him, except for a tower used as a prison, built at the corner of the bastide at the time of its construction. He then undertook the construction of the castle with his own money. He asked the king to reimburse the expenses, and the king accepted in May 1315. But in 1318, the central administration of London asks him to address the Constable of l'Ombrière.
This castle is called according to a legend the "castle of the White Queen". Only the enclosure with ramparts and a square keep, isolated in the middle of the enclosure, remain.
The construction of the castle began after 1314, during the reign of Edward II of England. At that time, he had chosen to make Molières a fortified base to exercise his authority.
The surrounding wall with a square base of 50 meters on each side was completed up to the level of the covered way. In the middle is a tower of six meters on a side which is the contemporary tower of the creation of the bastide. The construction of the castle was stopped at that time, as indicated in a deed of March 1320. The castle remained unfinished.
The castle was registered as a historical monument on October 12, 1948. It is a private property.
