The dean's St. Vitus' Church is the Gothic three-aisled basilica. It was built between 1407 - 1439 on the foundation of an older sacral building from 1309. During the 17th and 18th centuries the church was extended in the Baroque style and at the turn of the 19th century it was rebuilt again. The Gothic portal originates from 1410.
The tower in the western corner of the church is in higher grounds octagonal and it has a pyramidal roof. The northern side of the church adjoins with the Baroque chapel of St. John Nepomucene and with the chapel of the Resurrection.

The church is arched with the tracery and ribbed vaults. It has the Baroque and Rococo furnishings and the paintings on walls from the first half of the 15th century. The valuable statue of the Piety from about 1350 is situated inside too.
