Within the fort (and built at approximately the same time) is a Federal style, -story limestone troop barracks, consisting of five independent but adjacent sections. Each section contains a ground floor mess, two floors of barracks rooms, and an attic. Brick additions were added to the rear of the building in 1861, housing washrooms and kitchens. Next to the barracks is a powder magazine, also constructed of limestone. Additional buildings originally built within the fort, such as officer's housing, have long since been destroyed.
