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:
La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
