Bordered by Rue Saint-Jacques to the east, the smart Rue Sherbrooke to the west, and Saint-Denis and Atwater streets to the north and south, the city's commercial and cultural heart, also home to its most famous monuments and institutions, lies to the west of Old Montreal. Rue Sainte-Catherine is home to the upmarket stores and shopping malls, while Avenue McGill College is lined with the city's iconic 20C skyscrapers.
