A castle, originated in the early 14th century, enlarged in the Late Gothic. In the course of the Thirty Years War Martin Huert took over the castle. During his era a Late Renaissance palace wing with arcades was built. A unique fortification system with the usage of a sizeable connecting stone bridge. In the period of the reign of King George of Poděbrady the Czech crown jewels were temporarily housed here. Recently the castle interior is not accessible because of the renovation.
