The Castle tunnels

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

Layout
Long, fairly linear tunnel. A sentry bot named Sarge guards the door to the armory at the end, but the armory can only be opened during the quest Old Guns. There are bottles of Amontillado wine and a skeleton encased by brick which is a reference to The Cask of Amontillado by Edgar Allen Poe where the General's body is found.

Notable loot

 * Fusion core near the end of the tunnel
 * Laser musket in the room just before the fusion core.
 * Minuteman general's uniform including hat.

Appearances
The Castle tunnels appear only in Fallout 4.
