The MAS, short for Museum aan de Stroom, is located in the trendy Eilandje district. While the museum itself is worth a visit, you don’t need a ticket to access the panoramic rooftop. Take the escalators up to the 10th (or is it 11th?) floor and enjoy one of the best free viewpoints in the city. You’ll see the old port, the skyline, and on a clear day, even the outlines of the distant Kempen region.
The panorama is open Tuesday through Sunday from 9:30 a.m. to 10 p.m. (last admission at 9:30 p.m.).
