Fort Knox's thick granite walls were designed to deflect cannon fire from ships passing through the Narrows of the Penobscot River. These walls also enclosed a pentagon-shaped center that contained the heart and soul of the fort.

All of the fort's essential functions were protected at this center. Here, soldiers would have had access to cannons, cannonballs, guns and related tools that they could use to defend enemy approaches from the river and the land. In addition to shaping its military function, the fort's center also housed facilities necessary for soldiers' lives here.

Magazines

Two magazines in the southeast corner were probably designed to service the cannons nearby on both levels of the fort.

Officers' Quarters

It is likely that these rooms, with their fireplaces and large windows, would have been the fort's most comfortable living spaces. In fact, these rooms were probably some of the few living spaces that actually were used. When the troops from Connecticut were stationed at Fort Knox for a month in 1898, they outfitted at least one of these spaces for a library and reading room.

Spiral Staircase

Spiral staircases, examples of the fine craft of the stonecutters and masons at Fort Knox, were common in forts of this period. Without taking up too much valuable space, spiral staircases provided an easy way for soldiers to get from one level of the fort to another.

Cistern

As described by Capt. Thomas Lincoln Casey, this cistern was designed to be fed from a spring outside the fort and contained 27,000 gallons of water. Pipes from the cistern would have supplied water for the privies, as well as for other uses in the barracks building that was planned in the parade ground.

Storage Vaults

These underground storage vaults were built in the area originally planned for a bottom level of a barracks. Historical documents describe the vaults as used for storage of fuel such as coal.

Privies

The two rooms behind the doors on the lower floor were most certainly privies and have evidence of plumbing. These spaces would have been connected by outdoor walkways to a barracks building, planned but not built, in the parade ground.

Washrooms

In May 1864, Capt. Thomas Lincoln Casey, Fort Knox's engineer, wrote to his supervisor to discuss the arrangement of "privies, washrooms, etc. under the terreplein of the west front which were completed last fall." The rooms Casey described were very likely these rooms on the opposite side of the parade ground. Although no plumbing is apparent in these small rooms, they probably were designed as the barracks' washroom and storage area.

Ordnance Storeroom

Here, soldiers would have stored equipment for firing cannons, as well as other arms and armaments related to the fort. This ordnance storeroom once had wooden walls and racks for equipment.

Bakery

In addition to shaping its military function, the fort's center also housed facilities necessary for soldiers' lives here. One such room was the bakery, with ovens built into the masonry walls of the fort. The placement of a bakery in a fort's masonry structure is not unusual during this period of fort constructino. Indeed, such a location was both fireproof and safe.

Storeroom

This storeroom was probably designed for general storage of equipment needed to manage and operate the fort.

Magazine

This well-protected, carefully ventilated room would have held barrels of gunpowder or boxes packed with loaded cartridges. Military practices required many precautions to ensure that a magazine's gunpowder did not ignite. People entering a magazine had to remove their shoes or put rubber coverings over them. This ensured that iron pegs in boot soles did not come in contact with small stones or flooring nails and create sparks. In addition, all tools and hardware used in a magazine had to be made of wood or copper.
