Mason District is an area in the Capital Wasteland located on the west side of Potomac River in 2277. It is overrun by super mutants.


The Mason District mainly consists of a large flooded park surrounded by buildings, with a metro entrance in the south and north. Hubris Comics is at the northwest. In the flooded park, right outside Hubris Comics, are some super mutants with a captive.

Mason District can be reached through three underground tunnels:

Notable loot


  • There is a sniper's nest that overlooks the park, in which the skeleton of a long deceased sniper can be found on the knocked over chair they were sitting on, and the rifle near the body. The corner apartment at the intersection of Jarndyce Way and Dexter Ave contains the nest on the second level.
  • There is an inaccessible entrance to an unknown metro station in the eastern part of the map. This entrance contains two escalators, but they are fully blocked by debris.


Mason District appears only in Fallout 3.
