Old houses are being demolished to make way for new construction, rightly so. However, some are worth preserving as an architectural heritage, but what if they get in the way? Then, if possible, they can be housed in an open-air museum. That is what has happened in Bokrijk since the late 1950s. Brick by brick and beam by beam, old constructions are taken apart, numbered and rebuilt on the museum grounds. In this busy museum, there is animation on the weekends by volunteers, dressed in matching outfits, who also showcase old crafts and music.
