The church was built in the early 16th century. In 1590 it was renewed by the carpenter John of Mstów, who left his signature. In the 17th century, a tower was added to the west, which was demolished in 1922. At the beginning of the 19th century a brick chapel was added to the church. In the years 1955-56 the church was subjected to extensive conservation work which saved its existence.
It is a gothic, orientated, wooden structure, erected in a log structure, with walls and roofs covered with shingle. It consists of a wider nave and a three-side ended presbytery. There are porches from the south and west. The church is covered with a gable roof with a common ridge, supported on a gothic roof truss. The interior of the church is covered with flat ceilings. There are three late gothic portals ended in the so-called ogee arch, and a gothic window on the east wall of the chancel. Inside has survived the baptismal font from the 16th century and fragments of original polychrome. The basic shape of the temple has remained unchanged since its construction time.
