The Institute (location)

The Institute is a location in the Commonwealth in Fallout 4. It is the secret headquarters of the organization known as the Institute, and is located deep beneath the C.I.T. ruins.

Layout
The Institute is a large cylindrical-shaped subterranean city with 3 floors. Hallways wrap the outskirts of the cylinder leaving the middle section open for a large atrium of trees and fountains, with a helix-shaped elevator going to the surface levels where the teleporter is located. The upper two stories of the cylinder are residential and meeting rooms. The majority of activity takes place on the bottom floor.

Along the outer circumference of the lower floor are the 4 labs. Bioscience is the lab to the northeast. Robotics is to the southeast. Synth Retention is to the Southwest. Advanced Systems is to the Northwest. There are also supply rooms next to each of the labs in the lower section. Some of these are locked via terminals.

Towards the hub of the bottom floor are 4 recreational/common areas. To the north is the cafeteria, to the east is supplies/outfitting, to the south is a break/lounge area, and to the west is medical.

Bioscience
One of the larger labs, bioscience is filled with plants, and even some synthetic gorillas. Most notably, however, is a series of connected labs that have been closed off and abandoned, entitled "FEV Labs". These can either be accessed via a master terminal hack in the main bioscience lab, or a novice lockpick and run through an abandoned area guarded by several turrets and an assaultron. The main feature of the FEV Labs is a room with super-mutants in some sort of stasis tubes. "Brian Virgil Personal Log 0176" is located here next to the computer terminal. This room also contains the FEV serum for Brian Virgil.

You can also get the quest Building a Better Crop here from one of the scientists.

Robotics
Robotics is the smallest of the four labs by accessible areas, consisting of a single large room containing the Institute's synth assembler. A constant stream of synths is being produced here, being assembled in a pool in the middle before climbing out and walking through into the inaccessible Processing section.
