Earnscliffe

Earnscliffe is a grey limestone manor on Sussex Drive featuring pointed arches, intricate brickwork, and three stories built on elevated ground. The house overlooks the Ottawa River and sits prominently on the street with clear views across the landscape.

The house was built between 1855 and 1857 for John MacKinnon before becoming the residence of Sir John A Macdonald, Canada's first Prime Minister. This early connection to political leadership shaped its significance in the nation's story.

Since 1930, this residence has served as the official home of the British High Commissioner, embodying diplomatic connections between Canada and the United Kingdom. The building represents how important government roles shape a location's identity and purpose.

The property at 140 Sussex Drive is normally closed to visitors, with public access limited to special events like Doors Open Ottawa. You can still enjoy views of the exterior from the street and explore the surrounding area at any time.

The name Earnscliffe comes from an old term meaning eagle's cliff, reflecting the elevated location with views toward the Gatineau Hills. This naming connects the building's dramatic position to its natural surroundings in a poetic way.
