Church of the Assumption of the Virgin Mary, Baroque church in Zlonice, Czech Republic

The Church of the Assumption of the Virgin Mary is a single-nave baroque building with a cruciform layout and two towers with onion domes flanking the presbytery. It stands on a raised terrace above the square, where a medieval church preceded it. The west facade has bound pilasters and a triangular gable, with niches holding half-figures of St. Wenceslas and St. Adalbert by Stanislav Sucharda.

Construction took place between 1727 and 1744 under the direction of architect František Maxmilián Kaňka, replacing an earlier Gothic structure that had stood on the site. This change represented the shift toward baroque style that transformed many Central European churches during that period.

The church keeps the votive painting of Saint Florian from 1767, which shows Zlonice beneath the saint as it looked at the time. The organ from 1745–1746 was built by the organ maker Václav Stark from Loket. The dean Jan Adam Svoboda, who pushed for the new building, is buried in the church.

The church stands on a raised terrace above the square in the centre of Zlonice, reached by a staircase below the west front. The terrace was already used by the medieval predecessor church. The exterior was restored between 1992 and 1995.

The church has two towers with onion domes flanking the presbytery, not a single tower. The author was long disputed: some attributed it to Kilián Ignác Dientzenhofer, but archival sources now confirm František Maxmilián Kaňka.
