It features the Second Empire architectural style that was popular for prestigious buildings both in Europe (especially France, where the style originated) and the United States during the latter 19th century. Although somewhat more sober in appearance and lacking a towering central belfry, Quebec City's Parliament Building bears a definite likeness to the Philadelphia City Hall, another Second Empire edifice in North America which was built during the same period. Even though the building's symmetrical layout with a frontal clock tower in the middle is typical of legislative institutions of British heritage, the architectural style is believed to be unique among parliament buildings found in other Canadian provincial capitals. Its facade presents a pantheon representing significant events and people of the history of Quebec.
