Monaco, the Rock, Monte-Carlo and the harbour
Two square kilometres between the mountains and the sea, and two faces: the Rock, with the palace, the cathedral and the Oceanographic Museum, where the Principality keeps the look of a fortified village; and Monte-Carlo, with the casino, the palaces and the shop windows, around Port Hercule and its yachts. Everything is done on foot, by public lifts and stairways, from one level of the town to the next.
