Fort Edward National Historic Site in Windsor, Nova Scotia preserves the oldest blockhouse in North America, built in 1750 by Major Charles Lawrence to secure the overland route between Annapolis Royal and Halifax. The wooden blockhouse and surrounding earthworks are the only remaining structures from this 18th-century fortification, which served as a crucial base during the Seven Years' War, the American Revolution, and the War of 1812. The site holds painful historical significance as the location where Acadian families were detained following the 1755 deportation. Visitors can explore an exhibit within the blockhouse, examine interpretive panels around the grounds, and walk a 1.3-kilometer trail offering scenic views; admission is free year-round.
