The Centre is connected to the city's underground network as well as the prestigious InterContinental and St-James hotels. In the Ruelle des Fortifications, a statue of Poseidon's wife, Amphitrite is found at the fountain and further along the passageway is a remnant of the Berlin Wall, a gift to Montréal for its 350th anniversary. It stands on the former site of the old city's ancient walled fortifications.
