The entrance to the Castle tunnels is quite difficult to find if you are not doing the quest Old Guns, and is hidden and cannot be accessed unless you have unlocked the workshop for the Castle during the end part of the quest Taking Independence. Once you have the workshop unlocked, head to the East Tower of the castle and head into the corner room. Then, look to your left and there will be a pile of rubble which can be scrapped in workshop mode. Upon scrapping this rubble, the stairs leading down to the door to the castle tunnels will be revealed.
- Fusion core near the end of the tunnel.
- Laser musket in the room on one of the shelves just before the fusion core.
- Minutemen general's uniform and hat.
- 10 cannonballs are present in the armory with the rest of the laser musket components and artillery schematics.
- 7 full Montressor Amontillado bottles and 4 empty ones, found in a crate near General McGann.
The Castle tunnels appear only in Fallout 4.
Behind the scenesEdit
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, where the protagonist's enemy is lured into an underground vault, chained and then encased by a wall. The label of the Amontillado Bottle reads "Montressor, Amontillado, Bottled by: P. Edgar" is again a direct reference to the work of Poe and the protagonist, Montresor.
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 from a duel with Lt. Gustavus Drane. According to folklore, the soldiers lured Drane into the basement of the fort and walled him up alive, although this never happened in reality. Years later, Poe used this incident as inspiration for "The Cask of Amontillado."
