Statement of Significance

Description of Historic Place

Public Grounds of the Parliament Buildings National Historic Site of Canada is prominently located on Wellington Street above the Ottawa River in downtown Ottawa, Ontario. The site is comprised of the four Parliament Buildings (Centre Block, East Block, West Block and the Library) and the grounds surrounding them. The grounds are landscaped with flower beds, mature trees, an upper terrace and roadways; and contains commemorative monuments and statues of varying styles and sizes. The site also features several associated buildings recently built behind West Block. Official recognition refers to property no.08834, which includes Centre Block, East Block, West Block, the Library, and the auxiliary buildings built behind West Block.

Heritage Value

Public Grounds of the Parliament Buildings was designated a national historic site of Canada in 1976 because:
- it is a good example of landscape design.

Constructed between 1859 and 1865 in the Gothic-Revival style, the Parliament Buildings were initially conceived to house the government of the united provinces of Upper and Lower Canada. The government first occupied the buildings in 1865, and after Confederation in 1867 the buildings were occupied by the House of Commons, the Senate, and the departmental offices of the new Dominion of Canada. With the change of government, commissioning a landscape design for the grounds became an important concern.

In 1873 the Department of Public Works contracted well-known New York landscape architect Calvert Vaux to design a plan for the public grounds on Parliament Hill. Superseding a design by English designer Marshall Wood, Vaux's design was implemented during the second half of the 1870s. Vaux’s design accentuated the differences in elevation between Centre Block and East and West Blocks with the construction of an upper terrace and projecting bays and stairs. Three sets of stairs linked the two levels, and at either side, curving ramps carried the road to the primary entrance of Centre Block. His design also included various roadways to integrate the dominating Parliament Buildings with the departmental buildings. Small geometric flower beds, diagonal walks and a circular plaza with a fountain ornamented the lawn.

While Calvert Vaux’s design was being implemented, additional work was undertaken to develop less formal gardens and the Lover’s Walk to the north of the buildings, in accordance with the ideas of Chief Architect of the Department of Public Works, Thomas Scott. Although the outline of Vaux’s design is still evident, it has largely been superseded by other designs. For example, the fountain and the diagonal walks have been removed and the crisp outline of the terrace retaining wall has been blurred by shrubbery. Fourteen statues have also been erected since the implementation of Vaux’s design. The first statue built behind the buildings was that of Sir George-Etienne Cartier, unveiled in 1885. Other statues followed including those of Sir John A. MacDonald in 1895, Alexander Mackenzie in 1901 and Queen Victoria, also in 1901. Pathways, flower beds and an ornamental summerhouse were added behind the buildings in subsequent years, although the flower beds and summerhouse are no longer present, as parking needs replaced much of the early landscape design. The Public grounds of the Parliament Buildings is often the focal for national celebrations and expressions of democracy.
