The church was built in opus emplectum style and has the form of an aisled basilica with galleries, twin-tower west facade and two apses (west and east). Round turrets at the east were added during reconstruction after World War II. The church resembles the Wawel Cathedral founded by Władysław I Herman. It was rebuilt in 15th and at the end of 18th century and burned in 1939; reconstruction works ended in 1954. The main (north) portal is sculpted and dates back to the first half of 12th century.
