This building, The Aberdeen Pavilion, was the central hall of the Central Canada Exhibition, that took place in Ottawa, Canada every August between 1888-2010 with the exception of World War II. What began mainly as an agricultural fair expanded over the years to include a midway. The land around the Pavilion has been redeveloped in recent years and the fair no longer takes place but this beautiful building, designated a heritage site, is still enjoyed by the public and houses other events throughout the year. I took the photo on a sunny day this summer but I think it lends itself to black and white.
