A boat

The Monolith

The Monolith as integral part of the thematic presentation – alongside other more unassuming works, has become one of the most significant images of the Expo.02. The sudden presence of this geometric form, which appears so completely foreign in its surroundings, creates a new landscape. Yet it fits in with the landscape and like the landscape, it remains the same yet changes continually. Its rusty metal façade evokes images of industry, of harbors and wrecks. The massive cube, however, also harks back to the black stone of Mecca or Stanley Kubrick’s film 2001: A Space Odyssey”. This solitary object in the water also recalls memories of Arnold Böcklin’s painting “The Island of the Dead”.

If you approach the gigantic, seemingly inaccessible form on board the quietly gliding solar boat, you gain some notion of the technical mastery of the construction: a colossus, whose sides measure 34 meters in length, “floats” on a platform made of a hundred prefabricated hollow concrete components, and is anchored to the bottom of the lake with steel cables. Logically but paradoxically, a shipping permit was required for ist construction and operation.

After slowly circling the cube, the boat trip ends in front of the narrow entrance passage, which opens out into the spacious ground floor hall. The only light in this hall is created by the projection of the multi-media Swiss Panorama version 2.1. onto a translucent screen. On the upper levels, visitors can enjoy a magnificent view over the lake oft Morat and the historical Panorama of the Battle of Morat is displayed. Everything about this building reveals that the theme is time: by deconstructing points of reference. The Monolith is not merely a mighty presence in the landscape or a series of architectural sequences, thanks to its mysterious aura, it is a complete piece of art.
