The church of St. Bartholomew comes from the turn of the 14th and 15th centuries. Its oldest part is the chancel and sacristy, which occupied the former chapel of Holy Trinity. The brick naves and chapel were built in the 15th century. In later centuries, the renaissance chapel of the Blessed Virgin Mary was added from the south, and in the nineteenth century, the porch on the north side. In 1866-1872 a major renovation was carried out, and subsequent restoration works took place at the beginning of the 20th century.
The church is a three-nave structure, built of brick, only in the lower parts of stone blocks. The external solid shows traces of later remodeling. The front facade is crowned with a gable fragmented with blendes and characteristic for the baroque, corrugated line. Interior architecture has maintained a homogeneous gothic character. The triangular ended presbytery has a net vault, while the aisles have stellar vaults. The gothic chapel is covered with a rib vault. From the medieval furnishings of the temple, two lion-shaped head holders are preserved in the front door, and a baptismal font dated to the second half of fifteenth century.
Next to the church you can see a romanesque road milestone, set in 1151 in halfway from Kruszwica to Kalisz. It is considered to be the oldest road sign in Poland. It is carved out of sandstone and is about 2,5 meters high. Its origin is not explained, it is assumed that the founder could have been the palatine of prince Bolesław Krzywousty, Piotr Włostowic.
