The oldest part of the church of St. Mary, that is the nave, was founded in the fourteenth century. In the fifteenth century, a chancel was added and an arch between the nave and the presbytery. During the renovation of 1847, the sacristy on the north side and the south porch were added.
The medieval church was erected from rough stone. It consisted of a rectangular nave and rectangular, but shorter by one span chancel. The 14th-century nave has its original northern entrance portal and has an additional southern entrance from the 15th / 16th centuries. There is a trefoil window on the south wall of the nave on the west side, and two windows in the form of triforium on the east side. The southern wall of the chancel has a similar window, placed in the nineteenth century, adjacent to the blocked window from the 17th century. The northern side of the church has similar windows as the south, east of these windows comes from the fifteenth century. The chancel from the 15th century is narrower than the nave and separated from it by a pointed chancel arch. At the western end, the church has a gallery, which can be accessed by going up the spiral stairs.
