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 WWII. 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.
