Trakai is a small town in southeastern Lithuania; 23-km southwest of Vilnius. It is built on a narrow, elongated peninsula dividing Lakes Galvė, Totoriškės and Luka. These lakes form part of an interconnected group that consists of at least 30 larger or smaller lakes.
The castle is sometimes referred to as “Little Marienburg”. The construction of the stone castle began 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.
