The original Guardhouse, which is at what I suppose must be the West Gate. This Guardhouse was built as part of the initial fort in the 1820's, revamped in 1877 (adding video games and Slurpee™ machines, one would imagine) and then replaced by a cooler, hipper Guardhouse elsewhere in the fort in 1900. This large room was intended to hold 20 to 40 ne'er-do-wells.
