Medininkai Castle, located only 30 kilometres from Vilnius, commemorates the times of the Grand Dukes of Lithuania. It is a place where Vytautas the Great wrote letters, and where Kazimieras Jogailaitis spent his summers. However, the main function of the castle was defensive. The brick castle in Medininkai was built in the 14th century, and it was the largest of the square fenced castles in Lithuania.
Medininkai Castle, which survived for a long time and withstood many battles, lost its significance at the end of 15th century when it was destroyed by fire. The long-forgotten castle complex was revived in 2012. Today, there is a museum with four expositions and educational programs for students and adults.
