¹⁰Curiously, the 1896 drawing of Cahercalla by Westropp was the sole graphic representation of the fort we could locate on the web, nor were there modern references to the fort, nor could we find it indicated on modern maps. We were about to conclude that it had been destroyed at some point after Westropp's visit. But an April 2014 query to the very capable reference staff at the Clare County Library resulted in locating the fort just where Westropp said it would be, somewhat obscured by vegetation, in a Bing satellite view.
