Bermuda
Bermuda had around 90 coastal defense forts and batteries[1] scattered all over the island chain. Early colonial defense works constructed before the 19th century were primarily small coastal batteries built of stone having anywhere from two to ten guns. Some of these early forts and batteries are the oldest standing masonry forts in the new world. Later forts constructed by the royal engineers were much larger and more complex.

Canada
Many places in Canada which bear the name "Fort" were never military establishments. Many were simply stockades, log enclosures for fur trading posts of the Hudson's Bay Company or the North West Company. Many in the West were also originally police outposts set up by the North-West Mounted Police prior to European-Canadian settlement of the area. See also Category: Forts in Canada
