The Vilnius Castle Complex is a group of cultural, and historic structures on the left bank of the Neris River, near its confluence with the Vilnia River, in Vilnius, Lithuania. The buildings, which evolved between the 10th and 18th centuries, were one of Lithuania's major defensive structures.
The complex consisted of three castles: the Upper, the Lower, and the Crooked. The Crooked Castle was burned down by the Teutonic Knights in 1390 and was never rebuilt. The Vilnius Castles were attacked several times by the Teutonic Order after 1390, but they did not succeed in taking the entire complex. Its complete capture occurred for the first time during the 1655 Battle of Vilnius. Soon afterwards, the severely damaged castles lost their importance, and many buildings were abandoned. During the Tsarist annexation, several historic buildings were demolished; many more were damaged during the fortress construction in the 19th century.
Today, the remaining Gediminas Tower is a major symbol of the city of Vilnius and of the nation itself. Annually, on January 1, the Lithuanian tricolor is hosted on Gediminas Tower to commemorate Flag Day. The complex is part of the National Museum of Lithuania, one of the largest museums in the country.
