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. Once you either hack the terminal on the first try or fail to hack on the first try, the two Protectrons in the room will activate and become hostile.

Notable loot

 * 49 steel, crystal, and fiber optics 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.
