rakai is a historic city and lake resort in Lithuania. There are 200 lakes in the region, of which the deepest (46.7 m) is Galvė with its 21 islands. Island Castle is the only one castle in Eastern Europe that built in an island. The ruins of the Peninsula Castle are at the north end of town. A notable feature of Trakai is that the town was built and preserved by people of different nationalities. Historically, communities of Karaims, Tatars, Lithuanians, Russians, Jews and Poles lived here. Karaims (or Karaites) are a small Turkic-speaking religious and ethnic group resettled to Trakai by Grand Duke Vytautas in 1397 and 1398 from Crimea, after one of his successful military campaigns against the Golden Horde. The name of Trakai was first mentioned in Teutonic Knights chronicles in 1337. Because of its proximity to Vilnius
, the capital of Lithuania, Trakai is a popular tourist destination.
