Place des Nations Unies — United Nations Square — is the working hinge of central Casablanca. The square is not a destination in itself but a major pedestrian and tram hub where the Old Medina meets the downtown Art Deco core and the boulevards radiate out toward the rest of the city. The landmark clock tower on the western side, a re-erected 1908 colonial-era column, makes it one of the easiest orientation points in the city for a self-guided walk.

The square sits at the north-western corner of the downtown grid, with the Old Medina walls directly to the north and Boulevard Mohammed V running south-east through the early-modern quarter. The Casablanca tram has a major stop here, taxis queue along the eastern edge, and several radial boulevards spoke outward — Mohammed V toward the Art Deco core, Hassan II toward Mohammed V Square, and Houphouët-Boigny toward the port and the Hassan II Mosque to the west.

Most visitors do not plan a stop at United Nations Square — they pass through it as the connector between the medina and the downtown architecture walk. From the square the Hassan II Mosque is a fifteen-minute walk west, the Sacred Heart Cathedral is ten minutes south, the Old Medina starts immediately at the northern edge, and Mohammed V Square is five minutes along Boulevard Hassan II. Use it as the pivot when sequencing a downtown route on foot, and budget five minutes standing under the clock tower to orient before setting out for the next stop.
