Trinity Church

Trinity Church is an unmarked location in the Back Bay neighborhood of Boston in 2287. It is within Trinity Plaza.

Layout
There are two entrances to the church. One is through the main doors on the western side of the building, and the other is through a metal hatch leading to the basement of the church on the northeastern side of the building.

The church consists of an entry foyer, a main room, some small rooms upstairs, and a basement. In the main room, the floor has caved in, making it difficult to access the back of the church without jumping or taking an alternate path. A group of super mutants occupy the rear area of the church across the chasm on the main floor, and can easily spot the Sole Survivor upon entering the church. Several narrow stairwells link the upper and lower sections of the church, offering several paths between the upper, main, and lower levels. There is a cellar exit in the back of the church.

Notable loot

 * Astoundingly Awesome Tales issue #4 - On the lectern by the steamer trunk on the main floor.
 * Four overdue books – One is on a shelf in a small room down the stairs behind the lectern at the east end of the main floor. The second is on a shelf in the basement dining and drinking area. The third is next to a broken terminal in the basement. The fourth is standing on the table in the same room.
 * Vault-Tec lunchbox - In the nursery in the basement.
 * Super mutant wrist wraps - Behind an Expert-locked door on the uppermost non-attic floor.
 * Flux sensor - Inside the steamer trunk on the main floor. This item only appears during the Quartermastery quests.

Bugs
A locked door in the uppermost non-attic level (mentioned above, which contains super mutant wrist wraps) reads as having an "Expert" lock when moused over; however, it seems to actually be a Master lock and requires Locksmith level 3 to open.
