The Princes' Gates is a triumphal arch and a monumental gateway at Exhibition Place in Toronto, Ontario, Canada. Made out of cement and stone, the triumphal arch is flanked by colonnades on both of its sides, with curved pylons at both ends. The 350-foot-long (110 m) structure serves as the eastern gateway to the Canadian National Exhibition, an annual agricultural and provincial fair held at Exhibition Place.
The Princes' Gates was initially conceived in the 1920s, forming part of a larger redevelopment effort of the eastern portions of Exhibition Place. Work began on Princes' Gates in April 1927, and was completed several months later in August. The structure was initially planned to be named the Diamond Jubilee of Confederation Gates, with its opening coinciding with the 60th anniversary of Canadian Confederation. However, the structure was named Princes' Gates, after Edward, Prince of Wales and Prince George, Duke of Kent were scheduled to officially open the new structure. The structure was officially opened by the two princes on August 30, 1927. Since its completion, the structure has undergone several restorations. In 1987, the municipal government named Princes' Gates as a "structure of architectural and historic interest" under the Ontario Heritage Act.
