Fort Union Trading Post Historic Structures Report (Part II) Historical Data Section

During the 39 years of its existence, Fort Union underwent many changes. Some of these developments resulted in quite dramatic changes in appearance, such as the bourgeois' house rising from 1-1/2 to 2 full stories, and the addition of a third story to the southwest bastion. Each known structure is discussed separately below in order to bring together that which has been learned about each. A number is assigned to each structure known to have had a separate identity. Other structures or use-areas about which less is known or which were located away from the fort are also discussed below, but historic structures numbers have not at this time been assigned to them.
