A red brick castle is situated in an extremely beautiful place, at the confluence of the Rivers Nemunas and Neris. Historians consider that it is the oldest brick castle in Lithuania once known for its size, firmness and modernity – it was surrounded by two rows of defensive wall. The castle and its brave defenders blocked the pass for the crusaders to inner Lithuania, including Vilnius. The city of Kaunas started with the castle, but today it is used for playing music, showing theatre performances and organising festivals rather than fighting. The branch of Kaunas City Museum is opened in the castle. The museum organises many educational programmes.
