Parsons State Insane Asylum

The Parsons State Insane Asylum is a location in the Commonwealth in Fallout 4.

Getting In
Gaining access to the asylum is not straightforward. The interior can only be accessed during the mission "The Secret of Cabot House". In order to start this series of missions you first must kill all of the guards that are defending the asylum. You will then need to meet "Edward Deegan" who spawns in either Diamond City, Bunker Hill Monument or Goodneighbour.

Appearances
The Parsons State Insane Asylum only appears in Fallout 4.
