This second exhibition space created by Koohlaas is characterised above all by the metal coating of Cor Ten steel covering the inside and outside walls, treated with a special sealing glaze which gives it the highly unusual look of greased leather. The hues thus created are very warm, perfect for enhancing the beautiful colours of the paintings on display in these rooms: collections of immense value, containing works by Picasso, Matisse, Derain, Bonnard and other artists of similar status from the Hermitage in St. Petersburg.
To add to the versatility of the exhibition halls, the works of art are permanently fixed to the metal walls by magnets which give them the appearance of precious gems on display in a jewellery box. In an attempt to create an ideological link between the museum spaces and the more light-hearted hotel casino, a copy of Duane's "replicants" appears amidst the hotchpotch of the hotel boutiques, setting many of the tourists and visitors who throng the hotel aback.
Koohlaas' experimental construction of these two museums certainly offers an alternative to the urban growth forecast for Las Vegas by Venturi, who recognised the importance of "fun architecture" but believed it would be browbeaten by the values of the entertainment world. But Koohlaas proposes a new essence of the public space, which transforms the idea of fun at any cost that dominates this city into a way of opening up the doors to new possibilities for use, in a broader, philanthropic sense in which commerce and culture run along the same tracks.
