In sufficent time with 40th birthday of Olympiatower the highest situated restaurant of the city presented its new appearance. Indirect lighting of gently glimmering tombac-coloured ceilings and walls creates mysterious lighting of the '181'. During the blue hour starts a delicated interplay between sunset and refected artificial light.The cladding was delivered from low-volt-wire and satellite dishs. Luminaires were integrated into the cladding elements. So the barrier-free 360°view is possible. Rhythmically arranged LED-Lighting-points set a course on walls.The helical staircase to the rock-museum and to lavatories has a corepart orientated lighting which acts like a fan. An artificial light-window with seasonal changing themes welcomes the visitor on the viewing platform level.
