 The main outdoor area of The Hill is the quadrangle, formed by the arrangement of the parliament and departmental buildings on the site, and laid out in a formal garden fashion.This expanse is the site of major celebrations, demonstrations, and traditional shows, such as the changing of the guard, or the annual Canada Day celebrations.To the sides of the buildings, the grounds are set in the English garden style, dotted with statues, memorials, and, at the northwest corner, a Carpenter Gothic structure called the Summer Gazebo, a 1995 reconstruction of an earlier gazebo, Summer House, built for the Speaker of the House of Commons in 1877 by Thomas Seton Scott and demolished in 1956.
