The Castle

The Castle is a location in the Commonwealth in Fallout 4.

Background
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 tough mirelurk queen. These enemies must be defeated before the player can begin to build and attract settlers.

Layout
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, a chemistry workbench, a 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.

After progressing through the minutemen questline, the mud and mirelurk egg clutches will be cleaned out and the player character will be able to reopen the armory, allowing them to build artillery pieces at allied settlements.

Appearances
The Castle only appears in Fallout 4.
