Connaught Building, Government office building in downtown Ottawa, Canada
The Connaught Building displays Tudor Gothic architecture with sandstone walls, turrets, and a crenellated roofline at 555 MacKenzie Avenue next to the United States Embassy.
Construction started in 1913 and finished in 1915, initially serving as the Customs Examining Warehouse before becoming part of the Canada Revenue Agency headquarters.
The building bears the name of the Duke of Connaught, Queen Victoria's third son, who served as Governor General of Canada from 1911 to 1916.
The structure contains two basement levels and eight above-ground floors, following the 1971 renovations that modified the internal layout of the building.
The building features randomly coursed rusticated sandstone walls with granite plinth, Wallace stone details, and specifically carved windows throughout the structure.
