History of Grand Isle

The area was first settled in 1805 by Acadians fleeing from the British. Later, in 1843, the community was organized as part of Van Buren Plantation from Township 18 R3. Grant Isle Plantation was then set off from Van Buren Plantation in 1859, and it went on to be officially incorporated as a town on March 2, 1869. A few years later, in 1872, the town's name was changed to Grand Isle to commemorate the large island located in the middle of the Saint John River.

Today, that deep heritage remains a cornerstone of the community. In the village of Lille within Grand Isle, the Musée Culturel du Mont-Carmel occupies a decommissioned Catholic church listed as a historic site preserving Acadian and Québécois culture.
