The church in Rząśnik was first mentioned in 1368, but the original romanesque structure was created earlier. In the 15th and 18th centuries it underwent reconstruction.
The medieval romanesque church was built of unworked stones and cut stones in the corners. It consisted of a rectangular nave and a double-span, vaulted chancel. From the original building survived the walls, two walled windows in the north wall of the nave and the eastern window of the chancel. In the north wall of the nave there is a walled portal, the other is in the north wall of the chancel. Rib vault of the chancel is supported on massive geometric brackets. Later on, a gothic tower was added to the west.
