The Castle

The Castle is the former headquarters of the Minutemen in Boston in 2287. It is a possible settlement, and can be reclaimed during the Taking Independence quest. It is built into Fort Independence and is located to the East of The Gwinnett restaurant and brewery.

Background
Before the War, it was known as Fort Independence. The Minutemen repurposed it as their headquarters in The Commonwealth until a colony of mirelurks forced them out and took it as their nest. Preston Garvey asks the player to reclaim the Castle for a new generation of Minutemen.

Once the main stronghold of the Minutemen, The Castle is a potential settlement for the player, but it is teeming with mirelurks and houses a mirelurk queen. These enemies must be defeated before the player can begin to build and attract settlers.

Layout
Fort Independence is a star fort, consisting of five triangular bastions connected by walls. The walls are hollow and contain most of the fort's infrastructure, with only the workshop and the Radio Freedom transmitter out in the courtyard and two ruined gun positions on the walltop. The northwest and southwest walls have been all but demolished, and a sizable hole punched in the south wall as well, cutting off the west bastion--which contains the Castle armory--from access excepting through the Castle tunnels. The north bastion contains the Castle kitchen; the east, the General's quarters and access to the Castle Tunnels; the southeast, the barracks. The southwest bastion is completely inaccessible.

The Castle is initially occupied by a large group of mirelurks, and piles of mud studded with mirelurk egg clutches can be found all over the courtyard and all interior areas save the armory. Once the quest Taking Independence is completed, these will be cleared away and the fort made available for settlement.

Inside the fort is a Missile launcher and Flamer, as well as a small amount of ammunition for each. Once settled, it comes with five free beds, a medic stand, chemistry workbench, starter lighting and electrical cable system, and an industrial water purifier good for 40 units of water should the player reintroduce power into the system.

Inside the Armory is a cache of heavy weapons, a weapon and armor workbench, and three free laser turrets that can be stored or redeployed elsewhere using the workshop menu. Also present are the schematics for building the special artillery units. However, access to the Armory is impossible until the quest Old Guns is completed.

Access to the Castle settlement is done from the south via the main gate, and enemies will attack from this direction; behind the gate is a small and highly defensible room, which combined with the Castle's high and easily repaired walls makes it one of the safest settlements in the Commonwealth.

Behind the scenes
Toward the end of The Castle tunnels, near General McGann's body, is a crate of Amontillado wine. Opposite the wine is a skeleton seemingly entombed in a wall. This is a reference to Edgar Allen Poe's story The Cask of Amontillado. While he was serving at Fort Independence, Poe noticed a gravestone in the fort's cemetery dedicated to Lt. Robert Massie, who died on Christmas Day in 1817. The other soldiers told Poe that Massie had been killed in a duel with another officer, Lt. Gustavus Drane. Drane had never been popular with the enlisted men at the fort, and what little popularity he had vanished after he killed Massie. One night when he was drunk the soldiers lured him into the basement of the fort and walled him up alive. Years later, Poe used this incident as inspiration for "The Cask of Amontillado." The label of the Amontillado Bottle reads "Montressor, Amontillado, Bottled by: P. Edgar" again a direct reference to the work of Poe.

Bugs

 * The Minuteman in charge of broadcasting Radio Freedom may complain that the transmitter is not being powered and will stand idly when it is being powered. There is no way to command him, so you can not order him to sit down. So he may get stuck on a loop of complaining about a working transmitter and will not fix.
 * After opening the large armory door at The Castle, the inside button will not shut the door.
