Green Gables Heritage Place is a 19th century farm and literary landmark in Cavendish, Prince Edward Island, Canada. Green Gables served as the setting for the Anne of Green Gables novels by Lucy Maud Montgomery. Green Gables is recognized as a Federal Historic Building by the government of Canada, and is situated on the L.M. Montgomery's Cavendish National Historic Site of Canada. The National Historic Site itself is situated on Prince Edward Island National Park.
The building was initially erected by the MacNeil family during the 1830s, relatives of Montgomery who was born nearby the homestead. Interest for the Green Gables property grew in the decades after Montgomery published her novels; resulting in Green Gables purchase by the government of Canada in 1936. The government initially operated the home as a historic house that depicted 19th century farming life on Prince Edward Island. However, by the 1970s, plans were undertaken to refurbish the building to resemble Green Gables as depicted in Montgomery's novels. Since 1985, Green Gables, and the larger National Historic Site operate as a museum on Lucy Maud Montgomery and her novels.
