Fort Ingall was originally a British fieldwork built in Témiscouata-sur-le-Lac (formerly Cabano), Quebec, Canada, in 1839 for the Aroostook War between Great Britain and the US.

Excavations uncovered the foundations of several buildings, including the kitchen, officers' dormitory, powder magazine, and sections of the palisade, along with various artifacts such as porcelain, bottles, clay pipes, and military insignias.

[3] In 1972 the fort was reconstructed to its original dimensions using 19th-century construction techniques, funded by a $1 million grant from the Quebec Ministry of Cultural Affairs.

In the 1980s and 1990s, initiatives such as the creation of the Café de l'Adjudant and the Témiscouata Roseraie (the second-largest rose garden in Quebec) added cultural value to the site.

[3] In 2012 Fort Ingall was classified as a Monument historique du patrimoine québécois, the highest recognition for a heritage site in Quebec.
