Built in 1867 from lumber cut from cottonwoods in nearby river bottoms, this was one of five original officers' quarters. It outlasted the fort's barracks and stables, which were built of small vertical timbers called pickets, and its style was typical of 19th century army posts in the West. It is the only one left standing in the United States. Among the men quartered here was Gen. Ranald S. MacKenzie, who sent Indians back to reservations from 1871 to 1874. It was restored by the City of Jacksboro and is maintained by the Girl Scouts.
