Berlin’s oldest public park has provided relief from urbanity since 1840, but has been hilly only since the late 1940s, when wartime debris was piled up to create two 'mountains' – the taller one, Mont Klamott, rises 78m high. Diversions include expansive lawns for lazing, tennis courts, a half-pipe for skaters, a couple of handily placed beer gardens and an outdoor cinema.
