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.

Directly after the door behind the laser tripwires will be a room with another door with two protectrons at each side of it. In front of them all will be the treasures access terminal, which opens the door, leading to the Treasures exhibit. To the left is a hole in the wall leading to a storage area and the Master-locked door.

Behind the treasures access door will be yet another door with a button on a stand in front of it, which opens it, revealing the Treasures exhibit, a small room filled with numerous broken display cases and a raised second half that loops around the middle table and rail.

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.
