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:
