Located at the confluence of the Nemunas and Neris rivers, this impressive brick castle was built in the 14th century at the beginning of the Teutonic attacks. Unique for its double walls and the surrounding tunnel, many events and legends of Lithuanian history are attributed to it. Today, the castle is home to various temporary and permanent programs all year round. Join educational trips and exhibitions, mould a stove tile, and try your knowledge with the Castle Quiz. Just opposite the castle, St. George the Martyr Church is also worth a visit, for it is an important landmark of Roman Catholicism.
