The Tetrahedron is an architectural landmark of the North Rhine-Westphalian city of Bottrop. It consists of four interlocking steel pyramids placed on a hill and offering a view of the surrounding landscape. The Tetrahedron serves not only as a viewing platform, but also as a symbol for the structural change of the former industrial region in the Ruhr area.
