The Gothic church of the Immaculate Heart of the Blessed Virgin Mary was built at the end of the 14th or the beginning of the 15th century, although some researchers date the first wooden church to the years 1325–1330. At the end of the 16th century, it was enlarged by a tower, and in the 18th century by a porch on the south side. In 1714, the eastern gable was rebuilt.
The church was built of bricks on a stone foundation, as a spacious aisleless structure, without the chancel distinguished from the external block, with a sacristy and a porch on the north side. All external facades were reinforced with stepped buttresses, between which high, but quite narrow pointed windows were pierced. The church was covered with a gable roof, resting on the shorter sides on triangular gables. The eastern gable, rhythmicized with symmetrically placed pilaster strips, probably originally crowned with pinnacles, received a particularly decorative form. Stepped gables, decorated with blendes and pinnacles, also decorated the sacristy and the northern porch. The interior was covered with a wooden flat ceiling. At the end of the 16th century, a massive, four-sided tower was added to the church on the axis of the west facade.
