As far as downtown architectural landmarks go, it’s hard to miss the Toronto-Dominion Centre. Its sleek, black, rectangular appearance proudly demonstrates the modernist style of its architect, Ludwig Mies van der Rohe. While Mies projects like Westmount Square and the former Esso gas station on Nun’s Island dot the landscape of Montreal, just past the western end of Highway 401 sits the world’s largest collection of his work. A short distance northeast of the Detroit-Windsor Tunnel is Lafayette Park, one of the United States’ first urban renewal projects.
