Originally built as the post hospital in 1880, this structure has served many purposes throughout the years, including post headquarters and a schoolhouse. Today it serves as housing quarters for officers and their families.

The fort is one of the oldest active posts in the U.S. Army, dating from 1887. Just a few pages of history associated with Fort Huachaca would include the campaigns against Geronimo and Pancho Villa and the base for the Buffalo Soldiers. Since the mid 1950s, the base has served as the home for advanced testing of communications and electronic equipment and the Army Intelligence Center and School.

One downstairs room was the morgue for the hospital. Things stacked and placed in this room are unaccountably scattered all over the place shortly afterwards. Things hanging on the walls fall crashing to the floor because the nails holding them are pulled out of the wall by an invisible force. Doorbells ring so persistently for no observable reason that occupants of the house disconnect them. Many residents and neighbors have seen the whitish apparition of a woman moving through the house and standing at the front door. One corner of a room which was a ward in the original hospital stays markedly colder than all other parts of the house, regardless of the weather, and contains a chandelier that seems to refuse to operate at night but functions just fine in the daylight.
