Jamaica Plain Town Hall basement

The Jamaica Plain Town Hall basement is a location in Jamaica Plain in Fallout 4.

Layout
The basement used to be a janitor's area but it was changed into a pre-war cache, two months before the Great War. There are two ways to approach said cache. The left one is simple and requires one to walk through a gas-filled corridor after picking a Master-locked door. The right one is the original entrance covered by dozens of laser tripwires linked to turrets.

The laser tripwires can be rearmed by closing the final door using a nearby button and then salvaged again for high amounts of steel and fiber optics. Companions are very likely to enter the area and trigger the tripwires resulting in the turrets becoming active.

After entering through either entrance, the door to the cache is locked by a Novice terminal. If the player fails to hack it on the first try, the two Protectrons in the room will activate and become hostile.

Notable loot

 * 49 steel, crystal, and fiber optics (infinite amount if the red button at the end of the corridor is pressed to reactivate the laser trip wires) - Obtained if all of the laser trip wires defending the Treasures exhibit are disarmed.
 * The holotapes The Treasures of Jamaica Plain and Treasures inventory and the paper note Holotape instructions - On the table immediately within the Treasures exhibit next to a terminal.
 * 2076 World Series baseball bat - Found in a display case that's part of the Treasures exhibit, right of the entrance.

Appearances
The Jamaica Plain Town Hall basement only appears in Fallout 4.

Bugs

 * After all of the laser trip wires have been disarmed, they can be reactivated by pressing the red button at the end of the hall and disarmed again, yielding an infinite amount of materials.
 * Either a bug or a result of a patch; disarming the tripwires, even for the first time no longer yields any scrap material.
