The church was built in 1624–1646 by order of Lew Sapieha on a market square and replaced an older wooden church. It was destroyed by fire in 1743, all interiors and churchware were lost. In 1751 Mikołaj Faustyn Radziwiłł [pl] donated money for reconstruction. The architect A. Osikevich rebuilt the church in Vilnian Baroque style. Another fire damaged the roof in 1882. In 1900 the church's territory was fenced by a high stone wall with towers.
