Church of St. Bartholomew in Chełmonie was probably erected in the first half of the 14th century. At the beginning of the 17th century, it was renovated by the then village owner, Zygmunt Konarski. The nineteenth century brought a thorough restaurant with the addition of neo-gothic elements.
It is a gothic church, orientated, made of brick with the use of zendrówka arranged in zigzags in the lower parts of the chancel walls. The side walls are separeted by pointed windows. The presbytery is ended with a straight wall, on its axis from the eastern side, there is an unusually small sacristy. The eastern gables of the sacristy and the chancel are divided with pointed niches. The top of the sacristy is decorated with diagonal pilaster strips that pass into the pinnacles. Unusual for a small rural church is the architectural design of its interior. In the side walls of the chancel and the nave there are pointed niches. The interior is covered with neo-gothic ceilings with a semi-open roof truss.
