The church of St. Michael was erected in the 13th century, but its call and the circular plan of the church cemetery suggest, that it could have been built on the site of an earlier building from the 10th or 11th century. The earliest written references to the building date from 1291. During this period under the Norman rule, a settlement developed near a nearby castle, which became a royal borough with market charter. At the end of the Middle Ages, the castle fell into disrepair, and the village decreased to a small hamlet, with the temple remained, as a symbol of better times. In the 16th century, construction works were carried out at the church, probably from this period the southern porch comes from. A major renovation was carried out in the 19th century. It included a partial reconstruction of the walls, replacement of windows and a timber ceiling.
The church is an orientated building on a rectangular plan, consisting of a nave and a not externally separated chancel. On the west side there is a small tower, and next to it, at the southern wall of the nave, the sixteenth century porch. The oldest element of the temple’s equipment is the octagonal Norman baptismal font. The church has also preserved late medieval, painted rood screen, divided into six sections on both sides of the door.
