The initial hillfort of the Teutonic Knights in Panemunė (erected 1343) was replaced by a present castle built in 1604-1610. It was built by Hungarian nobleman Eperjesh who bought the surrounding lands from Lithuanian local inhabitants. It is a typical 17th century feudal castle with a defensive tackle, living quarters and farm buildings. The castle stands in a park on a high hill and is girdled by five cascading ponds. It was reconstructed around 1759 by Giełgud family.
The Panemunė castle was left to decay in the 19th century. Its valuable library was brought out, the former marvelous park of classicism style became feral. In 1925 Lithuanian government acquired the castle into a national possession. In 1935 the Panemunė castle and its surroundings where taken under responsibility of Lithuanian Culture department.
Nowadays Panemunė castle has 2 corpuses remained – the western including 2 towers and the southern. Panemunė castle belongs to Vilnius Art Academy which takes care about restoration of the castle and fitting it to science, education and tourism purposes. During the summer season the Vilnius Art Academy arranges there expositions of art works.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
