Island castle (XIV - XVI c.), Trakai
It is the only insular castle throughout Eastern Europe. It was built on one of the numerous islands in Lake Galvė. The castle was built as a defensive fortress. After the Battle of ?algiris/Gr?nwald the castle lost its defensive significance. It was turned into a ducal residence. Trakai Island Castle was the death-place of Grand Duke Vytautas. He died here on 27 October 1430. Later the castle served as a prison. In the XVII century the castle was desolated.
Island castle is one of the most often visited historical-architectural monuments in Lithuania. It houses a historical museum which has been working here since 1962. National events, festivals and concerts take place here.
