Tetrahedron in Bottrop, Steel observation tower and sculpture in Bottrop, Germany.
The steel tetrahedron structure rises 60 meters into the sky, supported by four concrete pillars on top of the Beckstraße mine dump.
Wolfgang Christ and Klaus Bollinger designed this industrial monument, which opened on German Unity Day in October 1995 as part of IBA Emscher Park.
The structure represents the transformation of the Ruhr region, converting former mining sites into public spaces through architectural and artistic design.
Visitors can climb three observation platforms through suspended staircases at 18, 32, and 38 meters, offering views of the surrounding landscape.
The third platform forms an 8-meter diameter ring with an 8-degree incline, moving slightly in strong winds due to its cable suspension system.
