Who Dares Wins
The Citadel is the east-coast headquarters of the techno-worshiping faction, the Brotherhood of Steel, in Fallout 3. It is built around and inside the ruins of the Pentagon Building. It's located north-east of the Arlington Library, and is extremely close to Jefferson Memorial.
You can gain access to this place after The Waters of Life quest, and start Power Armor Training from Paladin Gunny. This location is also a good source of caps since most of the BoS soldiers have power armor and laser weapons which sell for high prices, and the inhabitants of the Citadel usually forgive you for a death after 24 hours.
At the end of the Broken Steel Add-on main quest, Who Dares Wins, you have the option of destroying the Citadel, becoming a traitor to the Brotherhood of Steel. Doing so unlocks another armory in the Citadel, which holds a safe containing Callahan's Magnum.
The Pentagon or Citadel itself is by the sea and the heavy metal gates can usually be seen from a distance. Paladin Bael keeps watch at the gate with a Sentry Bot and a couple of other soldiers, usually armed with heavy weapons like Missile Launchers and Miniguns, and in same cases Fat Mans. There is a strong brotherhood presence all around the area, and when the Enclave occupied the purifier and heavily armed Enclave soldiers began to be dropped off by Vertibirds, tension rose.
A Squad of Brotherhood members led by Owyn Lyons (who was a Paladin at the time) were sent from their main base in California, Lost Hills, to Washington D.C. to look for advanced technology and check out the reports of Super Mutants in the area. While searching the Capital Wasteland, the Brotherhood came across a damaged, but still intact Pentagon. While searching the ruins of this former military masterpiece, they discovered Liberty Prime, a giant robot originally built by the U.S military to help them liberate Alaska from the Chinese, however Liberty Prime wasn't finished on schedule and after the bombs fell it was left abandoned deep in undergrounds of the Pentagon.
The discovery of Liberty Prime was enough to get Owyn Lyons promoted from Paladin to Elder, his next job was to set up a new Brotherhood base in the Citadel, continue looking for advanced technology and work on completing Liberty Prime.
The following main quests involve this location or are obtained here:
