The Athenaeum Club 1891
Built for the Athenaeum Club, this façade was designed by the architectural firm Denison and King in a Moorish Revival style, rare in Toronto. It features intricate brickwork, several Moorish window arches, and in the balcony, a cast-iron column with an exotic capital. From 1904 to 1967, the building was the Labor Temple - a home to the local labour movement, and host to key debates in Canadian labour history.
