The Potsdamer Platz Quarter is one of the most visited places in Berlin. Up to 100,000 people come here daily to experience the unique mix of shopping, entertainment and cosmopolitan flair – many of them are tourists, for whom orientation around the 68,000 m2 space, including underground car parks, plays a major role. Moniteurs won the competition to design the orientation system with a formal and thematic concept: the radial profile of the signs is derived from the typography of the neighbourhood itself. All three underground car parks were given clear designations and a colour-coded restructuring, which also served to lighten the atmosphere of the spaces. Above ground and underground orientation systems now seamlessly overlap and the graphics and content are interlinked.
