In the area of today's Piekary Śląskie there are very interesting Polish fortifications from the time before the Second World War. These are fortified shelters of the Fortified Area of Silesia, which was to defend the industrial region against German aggression. The preserved 24 fortifications were part of the point-defence 298 of the combat group "Brzeziny" and of the point-defence 304.7. In the unique shelter located in the district of Brzeziny the Association for Fortification Monuments "Pro Fortalicium" set up a museum chamber.
