Trakai Island Castle

Trakai Island Castle Trakai Island Castle (Lithuanian: Trakų salos pilis) is an island castle located in Trakai, Lithuania, on an island in Lake Galvė. The construction of the stone castle was begun in the 14th century by Kęstutis, and around 1409 major works were completed by his son Vytautas the Great, who died in this castle in 1430.

Trakai was one of the main centers of the Grand Duchy of Lithuania and the castle held great strategic importance. Soviet Communists restored the castle and established the Trakai History Museum there.
