Collegiate Church of the Holy Cross and St. Bartholomew

The church was founded in 1288 by Polish monarch Henryk IV Probus, who was eventually buried in the church after his death in 1290, when the church was still under construction. Construction was continued by, among others, bishop Nanker and parish priest Jan Stanko. The upper church (Holy Cross Church) contains an epitaph of bishop Nanker. 15h-century Polish chronicler Jan Długosz described the church as "beautiful and magnificent" following his visits in Wrocław. From 1502 to 1538 renown astronomer Nicolaus Copernicus was a member of the collegiate chapter. In 1821 Polish poet Julian Ursyn Niemcewicz listened to a Polish sermon in the church. After World War II, the lower church (St. Bartholomew Church) was used by ethnic Germans until 1956 and later by the Ukrainian Greek Catholic Church until 1997.
