The church was erected at the end of the 13th century on the site of a temple mentioned in 1207, probably built of wood. It was probably funded by the Dewins, the first owners of the town. In the Middle Ages, it was outside the town walls. In the 15th and 16th centuries it was rebuilt, among others was made new vaults. It served as the cemetery church of the oldest Żary necropolis.
The small temple is a structure erected from unworked, glacial erratic stones, one nave with a separate, narrower, rectangular chancel. In the nave a cross vault was installed, and in the presbytery net vault.
