The 15th century All Saints Church is one of the defining landmarks of Gliwice, and though modified through the ages it remains a stunning example of Gothic architecture. Recent excavations suggest that the immediate surrounds functioned as a cemetery from as early as the 12th century, while the brick church itself is a feast for the eyes, and stuffed with intricate statues of the saints. The tower offers sweeping views of the city when open (Sundays from 17:00 May-September for 5zł). Only Night tours are available from October - May (10zł tickets available at PTTK).
