Fort Edward is a National Historic Site of Canada in Windsor, Nova Scotia, Canada (formerly known as Pisiguit) and was built during Father Le Loutre's War. The British built the fort to help prevent the Acadian Exodus from the region. The Fort is most famous for the role it played both in the Expulsion of the Acadians (1755) and in protecting Halifax, Nova Scotia from a land assault in the American Revolution. While much of Fort Edward, including the officers quarters (burned down 1922) and barracks, has been destroyed, the blockhouse that remains is the oldest in North America. A cairn was later added to the site.
