There is a short, steepish rocky little dirt path that leads from Fort Mississauga's sally port down to the water, at which point one is treated to this excellent view of Fort Niagara's North Redoubt. Fort Niagara has two of those "redoubts," which are essentially the same thing as Fort Mississauga's Tower, but they're called redoubts, and Fort Mississauga's is called a Tower. We can't blame this on linguistic differences betwixt the British and Americans, because the British built and named those redoubts at Fort Niagara, after they had taken it from the French.

Also, there is a US Coast Guard station right next to Fort Niagara! As is only right and proper, because who knows what those warlike Canadians might get up to absent supervision.
