Characteristics
Designed by Jean Omer Marchand and John A. Pearson, the tower is a campanile whose height reaches 92.2 m (302 ft 6 in), over which are arranged a multitude of stone carvings, including approximately 370 gargoyles, grotesques, and friezes, keeping with the Victorian High Gothic style of the rest of the parliamentary complex. The walls are of Nepean sandstone, and the roof is of reinforced concrete covered with copper.
At its base is a porte-cochere within four equilateral pointed arches, the north of which frames the main entrance of the Centre Block, and the jambs of the south adorned by the supporters of the Royal Arms of Canada. Near the apex, just below the steeply pitched roof, are the tower's 4.8 m (16 ft) diameter clock faces, one on each of the four facades. The mechanical workings of the timepiece were manufactured by the Verdin Company, and are set by the National Research Council Time Signal. One level below, running around the circumference of the tower's shaft, is an observation deck. This was the highest accessible space in Ottawa until the early 1970s; the Peace Tower dominated the Ottawa skyline, as a strict 45.7 m (150 ft) height limit was placed on other buildings. That limit, however, was later rescinded, leading the Peace Tower to lose its distinction as the city's tallest structure. Cantilevered out at each of the four corners of the tower, at the level of the observation platform, are four 2.5 m (8 ft 4 in) long, 75 cm (2 ft 6 in) high, and 45 cm (1 ft 6 in) thick gargoyles made of Stanstead grey granite from Beebe, Quebec.
The tower's flagpole holds symbolic significance, and acts as the flagpole of the nation. As such, strict protocol surrounds the display of banners atop the Peace Tower, such as half-masting for national mourning, and showing the flag of the sovereign, that of any member of the Royal Family, or the flag of the governor general, when any of those persons are present on Parliament Hill.
