Gradac Castle was first mentioned in written documents in 1228. The castle island is mostly covered by a large Renaissance park that is neglected and overgrown. It includes a garden, remnants of an alley, and the mausoleum of the last owner (named Gusič), who was a businessman from Zagreb. There are plans to restore the castle and renew the park. The Municipality of Metlika repaired the roof of the castle to prevent further decay at end of the 1990s.
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.
