The Montreal Forum (French: Le Forum de Montreal) was an indoor arena located facing Cabot Square in Montreal, Quebec, Canada. Called "the most storied building in hockey history" by Sporting News, it was the home of the National Hockey League's Montreal Maroons from 1924 to 1938 and the Montreal Canadiens from 1926 to 1996. The Forum was built by the Canadian Arena Company in 159 days.
