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. 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.

Notable loot

 * Holotape instructions, a paper note on a table next to a terminal in the Treasures exhibit.
 * Two holotapes, The Treasures of Jamaica Plain and Treasures inventory, on the same table.
 * 2076 World Series baseball bat, in a display case on the north side of the room in the Treasures exhibit.
 * There are 49 steel, crystal, and fiber optics if all of the laser trip wires just prior to the room with the two protectrons are disarmed. (If you hit the red button at the end corridor you can start the trip wires over and can get an infinite amount of steel, crystal and fiber optics. This can be done even after destroying all laser turrets)

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.
