Montreal’s landmark city hall is known in French as Hotel de Ville de Montreal and is a National Historic Site. The city hall was designed by the architects Alexander Cowper Hutchison and Henri-Maurice Perrault in Second Empire Style, with construction beginning in 1872. In 1922, the building was destroyed by fire, with only the outer shell left standing. A new building was constructed inside the shell of the ruins, based on designs by the architect Louis Parant.
