Mennonites appeared in the vicinity of Kazuń in the late eighteenth century. One of the few extant traces of Mennonite presence is the former church situated ca. 500 metres from the intersection of roads number 85 and S7. The wooden church was built in 1892 to replace the former, also wooden church erected in 1823. The older structure had suffered destruction during the flood. The current shape of the building dates back to 1924. In that year, the former church was renovated to remedy World War II devastation. The church stands on a plot of land surrounded by old poplar trees, on a high stone wall base, with its gable facing the road. The external wall decorations, window frames, and quions carved into decorative bossage–all references to masonry decorations–are the highlights of the church in Kazuń. The intention behind these decorations was to emphasise the exceptional status of this building. The rafter-collar gable roof of the church is made of metal and supported with so-called ties. Double doors made from profiled planks lead into the building. A segmental arch crowns the top of the door. The present layout of the church interior varies greatly from the original one. After World War II, the building housed a communal office, a police station, and a school. At first, the building was divided into three parts. One third was occupied by the school and the teacher’s apartments, and two thirds served as a prayer room scantily equipped with pews and a preacher’s stand. Worshippers sat in pews perpendicular to the longer walls. The pulpit was at the centre of the end wall, opposite the entry door. The Kazuń religious community brought together Mennonites living in Kazuń, Cząstkowo, Sady, Markowszczyzna, and Secymin.
