Centre Block

Centre Block is a Gothic Revival parliament building on Parliament Hill in Ottawa, constructed from Canadian sandstone with a central tower and two flanking wings. The facade shows pointed arches, gargoyles and tall windows, while the interior presents vaulted ceilings, wood panelling and handcrafted stonework.

The current structure opened on July 1, 1927, after the previous building was destroyed by fire in 1916 during the First World War. Architects John Pearson and Jean-Omer Marchand designed the replacement with stronger fire protection and added safety features.

The name refers to the central position between the East and West Blocks on Parliament Hill, and chambers inside bear names of Canadian prime ministers and historical events. Visitors can see carvings of Canadian flora and fauna on ceilings and walls throughout public areas.

The building remains under full renovation until 2030, with parliamentary sessions currently held in other government buildings across downtown Ottawa. The Peace Tower stays partially accessible to visitors during construction work, though most interior spaces are closed.

The renovation project involves replacing 1,600 windows and restoring 250 stained glass panels throughout the building. Some original sandstone will be replaced during the work with new blocks from the same historic quarries.
