In the mid-13th century, a church with a brick chancel and a wooden nave was built in Mieronice. According to legend, it was funded by one of the magnates of that time, thanking God for finding his daughter lost in the forest. In the fifteenth century, it was decided to replace the timber nave by a stone one. At that time, the porch was added and the chancel windows were widened. In the 16th century, the sacristy was added. In the second half, for a time, the church was taken over by the dissidents. At the beginning of the twentieth century, a chapel was added.
The Romanesque presbytery, measuring approximately 7.5 x 6.5 meters, was built of bricks in the monk’s bond. Its only exterior decoration was a frieze made of intertwining arcades. Inside, the presbytery was covered with a cross-rib vault falling on corbels, decorated with floral motifs. The walls of the chancel in the 14th century were covered with polychromes. The nave, added in the 15th century, from the west, was reinforced with two corner buttresses. It had the shape of a rectangle, wider and longer than the chancel.
The church has retained its late Romanesque – Gothic form to this day, although the windows in the presbytery were enlarged later. Inside, there are faintly visible 14th-century frescoes on the walls, and a wooden belfry from the 18th century stands next to the church.
