Jefferson Memorial

Jefferson Memorial is a monument in the Capital Wasteland in 2277. It has five interiors that can be accessed.

Background
 The Jefferson Memorial was a memorial in Washington, D.C. dedicated to the 18th century politician Thomas Jefferson. Jefferson was the author of the Declaration of Independence and the third President of the United States of America. This 20th century monument was built on the bank of the Tidal Basin of the Potomac River, and was a major tourist site, second only to the Washington Monument. Unlike many other monuments in the city which were severely damaged or destroyed in the Great War of 2077, the Jefferson Memorial survived relatively intact into the 23rd century.

In the 2250s, the Memorial was selected by project lead James for Project Purity primarily for its location. The project's stated aim was for converting the Memorial into a water purifier where the river's water could be cleansed of radiation for use by residents of the Capital Wasteland. Project Purity was abandoned after James' wife Catherine died giving birth to their child and then picked up again 20 years later.

The statue of Thomas Jefferson can be seen in pristine condition submerged within Project Purity as it is activated.

In the add-on Broken Steel, the Purifier is operational. Brotherhood of Steel Knights and Scribes work inside and outside of the Memorial under the direction of Bigsley, overseeing the ongoing operation of Project Purity and organizing distribution of the aqua pura it generates. Additional Knights patrol the catwalks and shore for dying mirelurks, which apparently are being poisoned by the clean water. This may be due to the fact that mirelurks evolved after much of the Wasteland's water was irradiated, and can thus only survive in radioactive water.

The water caravans that depart from the Jefferson Memorial take a C-Route from the Memorial, west to Smith Casey's Garage, Northeast to Paradise Falls and then continues to the Republic of Dave where it turns around back on its route. 

Exterior
The exterior of the Jefferson Memorial has a variety of platforms as well as a few super mutant patrols. The entrance to the memorial is through the gift shop doors on either side of the platforms.

Jefferson Museum and Gift Shop
Upon entering the memorial from the gift shop side entrance you come upon a long hallway. At the other end of this hallway is a rubble filled room with a sewer grate hatch that is accessible and is a main part during the Waters of Life quest. Taking a right down the hall leads to some sort of lobby that has the gift shop and a turret emplaced on the roof, Bigsley's office during Broken Steel, to the left and ruined bathrooms to the right. Once past the second double doors you enter an area of ruined corridors and entrances to the Rotunda and the Memorial sub-basement. Before the Waters of Life quest these areas are filled with level depending super mutants including super mutant overlords in higher levels. This area includes many random junk items and one Nuka-Cola machine.

Jefferson Memorial Rotunda
The Rotunda is home to the Project Purity Purifier, the purifier itself is built around the statue of Thomas Jefferson. The Rotunda floor is covered in water and can not be swam through. The purifier has two levels of catwalks that hang over the pool of water that was the Rotunda floor. The first level catwalk encircles the purifier with a dead end at one end and a staircase leading to the second level on the other. The second level is an enclosed catwalk of steel and glass window walls. The activation panel is located here along with the Auxiliary Filtration Input system panel for which the Modified FEV can be injected into. Two leveled super mutants will spawn here, one on the first level catwalk and the other on the second level.

Memorial sub-basement
Going down the stairs you enter into a room filled with ruined desks and shelves and a Gore Bag left from the super mutants. In the middle of this room is a fence surrounded opening that looks down onto the flood pools on the below level. To the left of this opening is the Mainframe which can only be accessed during and after the Waters of Life quest. To the left is a hall leading to a room on the left and the stairwell to the below level. The room on the left of this hall is a small clinic with a examination table and medical and surgical tools on a tray.
 * This is the room where The Lone Wanderer was born.

Down the stairs you enter into what used to be the living quarters for the Project Purity Science Team filled with bunkbeds, footlockers, and filing cabinets. Past this room you come to a four way intersection of hallways. Taking a right leads to the flood pools. Taking a left leads you to the Flood Control switch and your father's sleeping quarters. Going straight forward leads you to a turn and a room on the right at the end of the hallway. This room leads to another room where the Auxiliary Power Fuse Box is located. This room and the flood pools area are connected here by a small hallway. This area is filled with level depending super mutants and the Memorial Sub-Basement plays a key role during the Waters of Life quest.

Appearances
Jefferson Memorial appears in Fallout 3 and its add-on Broken Steel.

Bugs

 * After The Waters of Life there are two non-hostile Enclave troops behind the memorial, but the only things they will say is "Yeah" and "Bye."
 * Sometimes, a caravan will be stuck inside the force fields.
 * If items are dropped on the surrounding structure they may fall through the floor and become unreachable but visible on return.
 * Crouching in third person with a hunting rifle and pushing the L trigger near the door (outside) may cause one of your legs to fold up at an odd angle.
 * In the western part of the sub-basement, and pump control area, various items such as cans, a ruined book, spatula and fork continuously fall through the floor.
 * The Rotunda room is backwards.
 * In the Rotunda room, in the little area with the pipes/pillars, there is a wall that you can walk through.
 * After the Take It Back! quest, if Fawkes was fired he may become stuck over the entrance and he will be unable to move or talk to the player.
 * If Broken Steel is installed you can go back to the Jefferson Memorial after the game ends. When you go into the main room you can see two terminals, one non-working and one that is, but there is no way to interact with this terminal.
 * After the Waters of Life quest, part of the fence is missing and so you can walk inside, also the Enclave troops within are non-hostile. The missing fence piece spawns during Take it Back!
 * On the left side of the rotunda, just next to the entry/exit, there is a fence you can get stuck behind. Only way of fixing it is by reloading an older save.
 * Upon entering after killing some super mutants if one has a sledgehammer/nail board it will float above the body.
 * If Broken Steel is installed you will encounter Brotherhood Scribes inside carrying book/holotapes, but if you kill them neither will be in their inventory.
 * Sometimes the sentry bot that spawns with the Enclave outside will spawn inside the ground making it impossible/difficult to kill.
 * It is possible to glitch your way pass the forcefields by jumping on the generator then past the forcefield with a high Agility.
 * After completing Take it Back! the water in the basin will still be irradiated.
