Strathmore is a mansion in Killiney, Dunleary-Rathdown in Ireland, and formerly the Official residence of the Canadian Ambassador to Ireland.^[1]

The house dates from the 1860s and was designed by Dublin-born Irish architect Alfred Gresham Jones and was extensively remodelled in the late 1940s by British architect Oliver Hill.^[2] It is located 10 miles (16 km) south of Dublin City Centre, 200 yards (180 m) from Killiney DART station. Strathmore is approximately 760 square metres (8,200 sq ft) in area.^{[citation needed]}

Strathmore sits on a 3.654-hectare (9.03-acre) triangular piece of land surrounded mostly by Strathmore Road, but faces Killiney Hill Road. It features views of Killiney Bay, Sugar Loaf Mountain, and northern County Wicklow.^[2] The grounds vary from formal gardens, walled gardens, extensive wooded areas to magnificent open parkland at the lower level.^{[citation needed]}

The mansion purchased by the Government of Canada in 1957 for Can$54,000, served as the Canadian ambassadorial residence for fifty years until it was sold for Can$17.6 million in 2008, despite lobbying against the sale by former Ambassadors and Irish diaspora groups in Canada.^[3]
