Kościół Wszystkich Świętych
Stout brick Gothic church built from 1250 and restored after a fire in 1711.
This is a tower built in 1322 as part of the city walls, plus an armory building. It was probably never a seat of the Piast royal dynasty, whose power was ebbing by that date. It's now a branch of Gliwice Museum.
Completed in 1900 as the Church of Sts Peter and Paul, this was promoted to cathedral in 1992 when Gliwice became a diocese.
