Designed by Daniël Stalpaert in 1656 as a storehouse for the Amsterdam war fleet, this impossible-to-overlook example of Dutch Classicism became the new home of the Maritime Museum in the 1970s. Even if you're not much of a nautical fan, the building alone is worth a visit. During the recent, extensive renovation, the courtyard of the biggest remaining 17th-century storehouse (free admission) was roofed over with a 200-ton glass-and-steel construction, the design of which
is a reference to compass roses and lines of longitude and latitude on old nautical charts. In the daytime, the roof casts ever-changing shadows on the courtyard floor (weather permitting); at night, hundreds of led lights on the rafters create the fairy-tale illusion of a star-spangled sky.
