St. Nicholas Church, commonly known as "Mikołaszek," is a historic late-Baroque religious building located in Krzanowice at Raciborska Street. It was erected in 1744 as a votive offering of gratitude for the town's deliverance from a Hungarian invasion, replacing an earlier wooden temple that had been mentioned as early as 1613. The church is distinguished by its neo-Gothic altar, which features sculptures of two bishops, and a classicist pulpit with a canopy topped by a figure of a lamb. On the side walls, visitors can see the 14 Stations of the Cross. It is also worth noting the small tower housing a little bell relocated from the cemetery chapel. In the 18th and 19th centuries, the church underwent several renovations, and a major overhaul was carried out between 1988 and 1991. In 1997, the wall surrounding the church was removed, leaving only the restored gate. St. Nicholas Church was entered into the register of historical monuments under number Op-615/59 (A/597/2020), confirming its historical and architectural significance in the region.
