BPS22 is one of the strongest reasons to stop in Charleroi rather than passing through it. The museum occupies a handsome industrial hall from the 1911 exhibition era, and its contemporary art programme fits the city's raw, post-industrial mood better than a polite white cube would.
Shows change regularly, with Belgian and international artists, photography, installation, and social themes. Pair it with a walk through the centre if you want to understand why Charleroi has become interesting to travellers who like difficult, urban places.
