Aon and National Bank towers

Aon and National Bank towers

Like twin sisters, these two towers occupy a prominent place in Montreal’s real estate market.

Sharing a six floor common underground base, these two skyscrapers, of modernist architectural style, are the only buildings to be constructed of steel in Montreal since the 1960s.

Designed by American architect Sylvia Gottwald-Thapar, the AON and National Bank towers, also known as Complex Maisonneuve, are connected to Montreal’s underground city.
