"City of Lost Angels"
That crazy lightshow over the Fort, what the fuck was that, some kind of thumb of God you called down? Amazing, fucking amazing.Lee Oliver in All or Nothing, or No Gods, No Masters if you upgraded the securitron army

Fortification Hill, or simply "The Fort," is a vast and heavily fortified base for Caesar's Legion on the east bank of the Colorado River, which serves as Caesar's main base of operations during his war against the NCR. Here, the Legion prepares for its second assault on the NCR at Hoover Dam. This is also the location where the platinum chip is used to install the upgrades to the securitrons, as the Fort is built above Mr. House's secret bunker. Caesar himself is stationed here, along with his Praetorian guards and the bulk of the Legion's Mojave forces in preparation for the upcoming battle.


To reach the Fort, the Courier must use the barge at Cottonwood Cove. However, it cannot be taken until certain events take place in-game. The Courier must either be invited when exiting The Tops after completing Ring-a-Ding-Ding! (by Vulpes Inculta, who will be waiting outside, or by Alerio if the player character has already killed Vulpes, eliciting a comment from Alerio), or when For the Republic, Part 2 has been completed to the point when one must report to Colonel Moore to inform her that the Great Khans have been dealt with.

On either side of the entrance are sleeping tents. To the north of the entrance past the tents is a small bar. In the center of the camp are the arena and Caesar's tent. To the southwest, there are more tents, another bar, and the weather monitoring station, which includes Mr. House's secret bunker. Standing on top of the hill near the entrance will allow a view of other tents and structures off in the distance that cannot be visited.

If the Courier has not yet been invited, the guards at the Fort may be hostile. If they travel to Cottonwood Cove with Boone, Boone will immediately attack all legionaries on sight, causing them to turn on the player character (unless a Legion disguise is worn).

Legion arena

Main article: Legion arena

The Legion arena is a small pit made of walls of scrap metal put together to form a post-apocalyptic colosseum. Here the Courier, if male, can fight slaves and captured NCR soldiers to the death for the amusement of Caesar's legionaries. Females will be told they are not allowed to fight in the arena and will not have this option. The only exceptions are: choosing to kill Benny (if he hadn't been dealt with at The Tops) by fighting him in the arena, fighting Lupa the dog in the arena in order to earn her brain, as a part of the quest Render Unto Caesar, or as a part of the quest Saving (or Savaging) Sergeant Teddy.

Notable loot

  • 500 surplus 5.56mm rounds - At the end of the northeast trench seen when first entering the fort.
  • Lupa's brain - Lupa must be killed for her brain. Antony may be spoken to while standing beside her, to arrange an arena fight with Lupa, for the quest Nothin' But a Hound Dog. Alternatively, Lupa may be attacked where she stands, but it will turn everyone at the camp hostile. Lupa's brain increases Rex's DT by 10.
  • Caesar's armor - Worn by Caesar.
  • Assuming he has not yet been killed by the player character, Benny will have his suit and Maria, a unique 9mm pistol.
  • Legion slave ledger - On a table on the lefthand side of Caesar's tent, in the righthand corner by some empty metal shelves.

Related quests


  • If choosing to fight Benny to the death in the arena, both participants will have machetes. He will have Maria on him when he is dead.
  • The Legionary guarding the entrance to Robert House's bunker pronounces Caesar with a soft "c" sound, unlike all the other Legionaries, who use a hard "k" sound.
  • There is a Museum of Technology poster in the first room of the weather monitoring station.
  • This location is actually far larger than the area that can be accessed. From various locations throughout the camp, one can see that the tents of the Legion stretch out far across the land surrounding the camp, though the gates to these areas are marked as "inaccessible."
  • Lupa's dead body will remain in the arena unless her brain is removed.
  • Blood spurts out of the training dummies when attacked with a power fist.
  • There is a crucified trooper on the left upon entering the gate.
  • The Legion has a strict policy of eradicating all use of drugs and alcohol among their men. Despite this, Legion officers and troops around the camp may be seen drinking beer.
  • If everyone in the Fort is killed with Boone present, he will acknowledge the death of Caesar and will proceed with a conversation about it.


The Fort appears only in Fallout: New Vegas.

The Fort is located in the same geographical area as the real world Fortification Hill, located on the Arizona side of Lake Mead, overlooking the Hoover Dam.
