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.
