In 1459 the market town of Poběžovice was bought by a lower nobleman Dobrohost of Drštka by Skořice na Rokycansku. At the latest in 1470, he left the keep and had built a late-Gothic solid water castle called Nový Ronšperk ('New Ronšperk'). Since then he was known as Dobrohost of Ronšperk, and Poběžovice was renamed Ronšperk. In 1864, the castle and the manor were bought by the noble family Coudenhove, later known as Coudenhove-Kalergi family.
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.
