Rotunda of Saint Catherine

It is the town's most valuable monument, and features one of the oldest fresco compositions in the Czech lands.

The building was originally a castle chapel, dedicated to Virgin Mary, built in the mid-11th century.

[1] The painting was commissioned by Konrad II of Znojmo on the occasion of his wedding with Mary (Marija), daughter of Uroš I of Serbia in 1134.

Apart from the donor couple, Konrad and Mary, the identity of the other depicted members of the dynasty is disputed among the historians.

With two exceptions being the Přemysl the Ploughman, the legendary ancestor of the dynasty, and Vratislaus I, the first King of Bohemia.
