The Tower's western corner. Does that attractive iron rainspout look like a handy way for an attacking American to clamber up to the top and meddle with Fort Mississauga's "Upper Battery," as the single gun affixed to the top of the Tower was known? Don't worry, that pipe is not only too high to reach up and grab, but it's also coiled with barbed wire! Of course barbed wire wasn't invented until the 1860's, and wasn't used for military purposes until 1895, by Portuguese troops in the addition of barbed wire may have happened at the same time that the hideous layer of parging was slapped on, which was during the First World War.
