The Capitol Building

The Capitol Building is a location situated within Washington, D.C. in the Capital Wasteland in Fallout 3.


Before the Great War, the United States Capitol Building housed the legislative branch of the government of the United States. It is located in Washington, D.C., on top of Capitol Hill at the east end of The Mall. The other side of the Capitol opens onto Seward Square. When discovered by the Lone Wanderer, it is a battle site between Super Mutants, Talon Company and later, the Enclave.


The Capitol Building complex is comprised of four areas, two of which can be directly accessed from the Capital Wasteland. The Capitol Building entrance from the west, in The Mall, exits into the Capitol Building west entrance area. The Seward Square entrance from the east is one of two doors into the Capitol Building west entrance.

Upon entering from the west, the other door into the Capitol Building east entrance is immediately ahead and to the right. The entrance to the third area, the Hall of Columns, is in almost exactly the same direction, east-southeast, but about six times further away, past the super mutant behemoth in the rotunda. At the end of the Hall of Columns are two stairwells; the door at the bottom of the second accesses the fourth area, the conference room.

A door in the northwest corner of the conference room area leads back to a room one floor above the southeast corner of the west entrance area, but it is effectively a one-way passageway, as when the player character enters, the floor of the upstairs room caves in and crashes down to the room beneath.


Inside the Capitol rotunda, the Lone Wanderer will initiate a battle between the Talon Company and the Super Mutants (these battles may differ by level). In the center of the rotunda is a Super Mutant Behemoth. Several other mutants of various sizes are also present. Two Super Mutant Overlords are present with Broken Steel.

The entry-point to the rotunda is on the west, just before the doorway is a passage north, which will lead to an Average locked computer controlling the three Mark VIII defense turrets inside the rotunda. It is set to not attack the Talon mercenaries, but the targeting data can be cleared. These rather formidable turrets can clear the area of hostiles including the behemoth without help from the player character.

  • A Tales of a Junktown Jerky Vendor is on a desk in a row of four desks separated by screens; it is the one with the fallen filing cabinet. The row of desks is just north of the long hallway running east and west to either end of the area.
  • A Pre-War Book is located on the fallen cabinet next to the desk with the Tales of a Junktown Jerky Vendor on it.
  • Nuka-Cola Quantum found in a break room east of the desks with the pre-War book and the Tales of a Junktown Jerky Vendor.
  • A Lying, Congressional Style can be found south of the Capitol Building east entrance at Seward Square, in a Pulowski Preservation shelter.

Hall of Columns

  • D.C. Journal of Internal Medicine on the upper level. A Talon Company sniper is stationed on a bridge, and the book is on a railing facing south. If it is not there it was likely knocked down in the firefight and can be found on the floor below.
  • Chinese Army: Special Ops Training Manual behind a Hard locked door accessed from a small hallway found near a turret and a locked turret control terminal in the middle of the hall on the west side.

Conference Hall


  • When fast traveling from another location to the east entrance, an Enclave vertibird will pass and carpet bomb everything in front of the player character with mini nukes. This has also been observed occurring immediately upon exiting the Capitol Building using the east entrance.
  • With Broken Steel, when exiting the Capitol Building, facing the Washington Monument and the trench networks, there will usually be a super mutant overlord patrolling the area, often on the steps to the left or right (but sometimes to the right, just outside the door).
  • The Talon Company merc in the rotunda wielding the Fat Man does not carry ammunition for it and fires it via script only once, at the super mutant behemoth. When approached, the merc will quickly and continuously switch back and forth between hostile and friendly, and can even be spoken to. He will never directly attack the player character, even if fired upon. However, in the chaos of the skirmish with the super mutants, it is possible to be caught in the blast when the merc fires it. Should he perish, it is also possible for one of the other combatants to pick it up and not suffer any restrictions on its use against the player character.
  • After The Waters of Life quest, the Enclave will establish a camp to the left of the main entrance.
  • The building is pictured on the front of Lying, Congressional Style.


The Capitol Building appears in Fallout 3. It also appears on a book cover in Fallout 3 and Fallout: New Vegas and in the Atomic Command game in Fallout 4. It is mentioned in Fallout 76,[1] and is printed on the front of the Treasury Notes introduced in its update Wastelanders.

Behind the scenes

  • On May 8, 2007, Bethesda Softworks released a piece of Fallout 3 concept art by Craig Mullins depicting the Capitol after the Great War. This picture appeared then in an apparent terrorist threat, said to be shown in an Islamist forum as a real life would-be scenario, according to media.[2]

  • Playstation 3Playstation 3 Although it may well be intended by the developers to prevent players using the behemoth's size to their advantage, the super mutant behemoth cannot be damaged from outside the rotunda room. However, if you use grenades it is still possible to damage it from outside the room.
