Elgin and Winter Garden Theatres
Designed by New York architect Thomas Lamb for the Loew circuit, this double-decker complex was unique in Canada, and included many features later found in movie palaces. The lower theatre, with "Renaissance" decor, opened in late 1913. It shared its vaudeville and movie shows with the smaller Winter Garden above, which opened in early 1914 and was extraordinarily decorated with real beech leaves and garden murals. The Winter Garden was closed in 1928, and remained essentially untouched for over half a century.
