This church in North Bohemia was built from 1597-1604 as a castle chapel. The central motif of the unique altar with alabaster reliefs is an unusual family tree of Jesus Christ. The rib net vaulting refers to an earlier tradition, while the diamond portals are a typical feature of the Renaissance; the double-height tribune galleries relate to the Protestant faith. The architectural rendering of the interior of the church, as well as the exterior, is entirely consistent with the Saxon Renaissance style. The single-nave Church of St. Florian in Saxon Renaissance style is part of a significant chateau complex built during the Renaissance and Baroque periods. The church was built as a private Lutheran Chapel of Our Lady serving the family of the owner and the staff; the consecration to St. Florian did not occur until the establishment of the Roman Catholic parish of Krásné Březno in 1897. In 2008 the church was declared a National Cultural Monument, and it underwent a complete restoration (2011-2013). In 2014 a restoration of the main altar was carried out. From April until September there is a tourist guide service in the church on weekends and public holidays. Visits on weekdays can be arranged throughout the year – by appointment. The church is the only monument open year-round in Ústí nad Labem.
