Church of St. Mary was erected in the 13th century thanks to the support of Norman lord William Fitzmartin. It was rebuilt for the first time at the turn of the thirteenth and fourteenth centuries or a little later, then in the fifteenth century. It was renovated in 1879.
The church consists of a rather long rectangular nave and a rectangular chancel, shorter, but of the same width. On the west side, a late-medieval, four-sided tower adjoins the nave. It has buttresses in the corners, a communication turret on the south-eastern side and a parapet. The arms of a wide transept adjoin the nave from the north and south. Both are two-bay, with each bay covered with a separate, gable roof mounted on a triangular gable.
As a result of the early modern renovation, the church was enlarged by the northern porch, and the southern wall of the nave was largely rebuilt. The windows of the temple were also replaced during renovation works. Inside the church there is a baptismal font from the 13th century.
