As a nocturnal landmark of the documenta city, the world's first permanent laser-light artwork links historical architectures of different functions and epochs into a network of spatial and temporal references. It connects octagonal cornerstones of Kassel's cultural landscape.
Compared to 1977, the lines have been slightly modified today. Starting from the tower at the Museum Fridericianum, a green and a red beam lead to the Hercules Octagon. At the same time, a green beam touches the tower of the Hessisches Landesmuseum.
Another beam aims from the side of the Fridericianum at the central building of the Orangerie, where it is split three ways to follow the Baroque axes of the park. In this way, the coloured network of light above the city forms an immaterial map of the city of culture, which aims to encourage people to retrace the city's history.
