Pictured is Trakai Island Castle, located on a island on Lake Galvė. The construction of the stone castle began in the 14th century by Duke of Trakai,  Kęstutis. His son, Vytautas the Great completed a major part of the castle around 1409. The castle went into disrepair in the 17th century. A major reconstruction began in 1946 and was finished in 1961. It is a major tourist attraction.
