About Antwerp

The Cathedral of Our Lady holds Rubens altarpieces beneath its single completed tower, and the Grote Markt's guild houses sit a few streets away. MAS, the museum on the old docklands, has a rooftop viewpoint over the Scheldt, and the Diamond District and MoMu fashion museum round out the city's other identities. The mildest weather falls between June and August, while May and September are quieter shoulder options.
