Guardhouse
"The guardhouse is built of stone, in the same style and on line with the barracks. It consists of an east room for general prisoners 18 X 22 feet and 11 ft. high. Lighted and ventilated by two large windows extending to the floor. The windows are secured by stout transverse iron bars. There is also a ventilator in the ceiling similarly secured, connecting with the general ridge ventilation of the building -- the attic space being open. This room communicates only with the guardroom form which it is separated (sic) by an iron barred door. The central room is occupied by the guard, and is of the same dimension as the room just described, but is without a ceiling. There is but one means of exit, a central front door. The western third of the building is occupied by eight arched stone cells, with heavily studded pecan wood doors, harder even that the iron or stone. There are four cells on either side opening into a central corridor, which is also of arched stone. The cells are ventilated by small barred windows about a foot square in the walls, and a corresponding opening in the door. Their dimensions are such as to give about 325 cubic feet air space per cell. The corridor is ventilated and lighted by a large barred window. The building like the barracks is surrounded by a portico, and has two small external rooms on the northern or rear angles, one intended to be used by the officer of the guard, and the other for securing such tools as the prisoners use at work. Notwithstanding its apparent security, seven prisoners made their escape by cutting first through the floor of the general prison room and then through its wall." ~ Fort Concho Medical History Record, May, 1871
Today, there is no visible sign of the Guardhouse left and a street crosses the original location of the building. Since the street has been closed the possibility for reconstruction of the Guardhouse exists.
