The church in the village of Ystradfellte was probably built in the 15th century, and in the 16th century enlarged by a tower and perhaps by the present chancel. In the second half of the nineteenth century, it was thoroughly renovated. Among other things, the roof truss in the nave and window frames were replaced, although the newly inserted ones imitated the appearance of earlier ones, probably from the 17th or 18th centuries. The last renovation works of the church were carried out in the 1970s.
The church consists of a rectangular nave and a lower and short chancel of the same width, closed on the east with a straight wall. The tower, built in the 16th century on the axis of the west facade is four-sided, crowned with battlement and parapet on protruding corbels. An open roof truss was used inside the nave and chancel, while the chancel has been preserved in its original barrel form.
