 The post was originally called "The Elbow" or "Bow Fort".Captain Brisebois attempted to name the fort after himself, but due to his unpopularity, it was renamed Fort Calgary in 1876 by Colonel James MacLeod, after Calgary House, a castle at Calgary Bay on the Isle of Mull, Scotland.With the decline in the whiskey and buffalo trade, the fort was down to four constables by 1880.
