The town is dominated by the state-owned Bečov Castle and Chateau. Originally a Gothic castle from the beginning of the 14th century, it was badly damaged during the Thirty Years’ War and subsequently abandoned. In the early 18th century a magnificent baroque castle was built in the castle’s vicinity. The grounds are complemented by a beautiful Italian terraced garden.
The biggest attraction of Bečov Castle is a reliquary of St. Maurus from the beginning of the 13th century, whose value is comparable with the Czech Crown Jewels. This unique Romanesque relic of European importance, a gilded box set with gems, encasing the remains of several saints, was found buried in the castle chapel in 1985.
