Once the core of the Massachusetts Bay University, with many lecture halls and offices for its staff and students, the Hall was adapted over the years for the needs of wastelanders and then mirelurks. Rooms that once served to educate students were repurposed as a hardware store, a workshop, or a sleeping room, while the disused parts of the Hall were taken over by mirelurks. The vast lecture rooms in the back are apparently the optimal environment for laying eggs and raising their young.
Most of Sedgwick Hall is restricted by Expert-locked doors on both stories to the east, and a Master-locked door to the south leads to the Dean's office. To the north on the second floor is what used to be a tools shop, on the opposite end is Jacq's terminal, and a stairway that leads up to the third floor is between them. This small home contains a cooking stove and a bedroom.
The Expert-locked doors lead to a flooded lecture hall, and the busted wall to the south leads to another lecture hall. The ground floor of this hall has an Average-locked door to the Dean's office, while a collapsed floor leads to the another part of the second story.
This reception room has a staircase leading up to the third floor classrooms, which are littered with holes in the floor. The only notable rooms are a professors office in the north (where Jacq and her duffle bag are) and a door in the northeast that leads back out to the Commonwealth.
- Mini nuke in the northern office on the third floor.
- Jacq's holotape is on Jacq's terminal.
- Jacq's note is in Jacq's duffle bag.
The Sedgewick Hall appears only in Fallout 4.
