A complex, bold and amazing exposition space, a museum without collection, the Kunsthal presents culture in the widest sense of the word: old art, new art, design, photography - from elitist to popular. The site presented a dual condition: the southern edge is bordered by the Maasboulevard, a 'highway' on top of a dike. The northern side, a level lower, faces the Museum Park - conventional contemplation. With these given, and the fact that these crossings would divide the square site into 4 parts, the challenge was: how to design a museum as 4 autonomous projects - a sequence of contradictory experiences which would nevertheless form a continuous spiral circuit.The pedestrian ramp is split, with a glass wall separating the outside, which is open to the public, from the inside, which is part of the circuit. A second ramp, running parallel and reversed, is terraced to accommodate an auditorium, and beneath it the restaurant. On the level where the 2 ramps cross, is the main entrance.
