MAS

Antwerp


Opened in 2011, MAS is a 10-storey complex that redefines the idea of a museum-gallery. Floors are designed around big-idea themes using a barrage of media, from old master paintings and tribal artefacts to video installations. But many people come just for the views over the city (no ticket required), which transform as you climb somewhat laboriously by a series of escalators and three flights of stairs (no public lifts).

The intriguing 2nd-floor treasure chamber is also free, as are three small outside exhibition pavilions. The 8th-floor sitting area is an open-to-all study space with seating and sweeping city views.
