Royal Battery National Historic Site, located within the Fortress of Louisbourg National Historic Site in Nova Scotia, is an archaeological site that dominates the north shore of Louisbourg Harbour. Appearing as a low grassy ridge, the outline of the battery’s ditch and glacis are still evident, as are the mounds that mark the remains of the flanking towers. The official recognition refers to the archaeological resources and landscape of the designated place in their existing spatial relationships.
