Mir castle is the main landmark of Belarus and, of course, in small city of Mir. It is an object that was inscribed into UNESCO World Heritage list in 2000. Built in beginning of 16th century at first it was for defensive purposes with the walls around. In 1568 castle was taken under the rule of famous rich Lithuanian family Radziwills. They changed castle appearance more to the palace view.
Castle has gothic renaissance style appearance. I like the way that all the towers of castle is different. Now some parts of castle are still being reconstructed, but it could be visited inside. We visited one tower and the ceiling with torture room.
