Megaton

 is a sprawling settlement south of Springvale and west of Grayditch, set in a crater and surrounded by impenetrable walls. It is one of the two largest civilian settlements in the Capital Wasteland, with 28 named inhabitants, and several Megaton Settlers.

Megaton should be the first populated town the player encounters after leaving Vault 101. Its proximity to Vault 101, its distinctive silhouette, and the relatively straight route make it extremely difficult to miss, and it will very likely be the first trace of civilization the Lone Wanderer encounters.

Background
Megaton was built by a large group of people who originally planned to seek shelter in Vault 101 but were denied access. So without shelter, they sought refuge in a large crater made by a large commercial plane crashing into the ground, probably as a result of the electromagnetic pulses generated by a nuclear detonation. They then constructed a place to call home out of pieces of metal/aircraft found nearby at a decimated air station. They were aided by the Children of Atom, who worshiped the undetonated bomb in the crater they were building around.

The plane
The large plane still can be seen in pieces throughout the town. The cockpit and nose cone are built into Craterside Supply apparently housing inaccessible living space to Moira. The main section of the fuselage is used as the armory, and the rear end of the plane is on the roof of Lucas Simms' house providing an extra sniper nest and speculated residence to Stockholm. You can get there via a trap-door in the ceiling of the Sheriff's house. The wings make up the two large "fins" that are symmetrically aligned next to Megaton's main gate, and the two engines are separated. One is used to work the pulley mechanism for the main gates, and the other one is above the path to the common house providing breeze.

First contact with Vault 101
In February 2241, a expedition party sent by the Overseer of Vault 101 contacted the residents of Megaton. Initially, the residents were cautious with these strangers before they eventually accepted and welcomed them into the settlement. Two Vault residents, Agnes and Lewis, were appointed as Vault ambassadors to Megaton by the expedition leader Anne Palmer. A record of this expedition was archived in the Overseer's terminal.

Boppo's raid
In 2277, a gang of Raiders established a base camp at Springvale Elementary School, with the purpose of mining their way into Vault 101. Some of these gang members, led by Boppo attempted a raid into Megaton. The attack ran afoul of Megaton's defences and her determined defenders. The town's sheriff, Lucas Simms, killed the leader of the raiding party.

Layout
Megaton is roughly circular, with a central plaza around an atomic bomb resting in a puddle of radioactive water. Starting in the north and proceeding clockwise, the plaza is ringed by The Brass Lantern, Mister Burke's House, Children of Atom, and Megaton Clinic. Pathways lead from the plaza to the gate of Megaton, Craterside Supply and the Common House. A major attraction of the plaza are the sermons of Confessor Cromwell.

Around the central buildings, a ring of buildings is built higher up in the crater. The Water Processing Plant and Moriarty's Saloon can be found here along with most of the inhabitants' private houses.

Trivia

 * Megaton backwards is notagem. Not-a-gem.
 * Megaton is likely based on an "old west" theme. Many elements of this are observed in the town such as a sheriff (with a cowboy hat) and deputy, a saloon, a general store, and many outlaws and brahmin (cattle) ranchers.

Japanese version
In the Japanese version of Fallout 3, the quest to blow up Megaton has been completely removed due to its "parallels to real historic events" quotes Official Xbox Magazine. They are referring to the atomic bombs that were dropped on Hiroshima and Nagasaki in 1945.
