Rivet City Rivet City is a city located inside a decaying , beached aircraft carrier in Washington , D . C . , in 2277 . It is the largest , most developed and scientifically - advanced settlement in the Capital Wasteland . Its inhabitants live in individual rooms and enjoy relative safety and security inside the aircraft carrier . A number of guards rotate 24 hours a day to protect the ship from raiders , super mutants , mirelurks and any other threats to the city and its inhabitants . Rivet City includes a shopping area , as well as an American history museum , science lab , church , clinic , bar and even a hotel . Background . Rivet City is located inside an aircraft carrier which was docked at the during the Great War , and was stranded when the water level in the Anacostia and Potomac rivers dropped . The carrier was inhabited by raiders in the upper decks and mirelurks in the lower decks until remnants of the Naval Research Institute decided to move in because of its strategic importance and its working hydroponics bay , which was used to set up a research lab . The prosperity of the science lab and the relatively safe location of the ship attracted many wastelanders who also settled inside . Super mutants attempted to invade the ship , forcing Seagrave Holmes and other settlers to reinforce and repair part of the carrier to make it defensible and safer . The rest of Rivet City grew up around the lab . The settlement itself was founded in April 25 , 2239 , when Horace Pinkerton , Annette Holmes and Brad Danvers decided to form a council to act as a governing body to look after Rivet City and the needs of its people . Many years later , a scientist by the name of Madison Li arrived at Rivet City in 2258 to begin Project Purity , and co - opted Pinkerton ' s staff . Pinkerton became jealous of Li , left Rivet City and began living in the bow of the ship , which by this point had separated from the rest of the hull . By 2277 , Rivet City is the sole supplier of radiation - free food in the Capital Wasteland , trading it for essential raw materials with other communities . Location . Rivet City lies in the most southeastern part of the map , near Anacostia . It is easiest to reach by following the eastern side of the Potomac River , crossing near the tepid sewers or at the Citadel or by swimming across from Arlington Library . It is also a short walk from the Jefferson Memorial . On the steel structure across from the aircraft carrier itself ( near Carlos the beggar ) , there is an intercom box that must be used to extend the bridge . After a brief conversation with Harkness , the chief of security , he will grant entry to Rivet City . Layout . Exterior . Northwest of Rivet City is a super mutant camp . There may be super mutants and sometimes a captive that can be rescued . As a notable item there is a " Lying , Congressional Style " skill book by some sleeping mats near several boxes of ammunition . South of Rivet City , there is a shipwrecked boat surrounded by radioactive waste . The boat contains ammo boxes and a locked first aid box . Interior . To access Rivet City , climb to the top of the tower near the Rivet City map marker ( frequently , there will be a trader waiting at the base of the tower ) . There is an intercom near Carlos . When activated , a bridge will extend from the ship . Rivet City contains a large and thriving marketplace , as well as other institutions , such as : Fortunately , Rivet City is quite well signposted , unlike the Citadel . On the upper deck the Lone Wanderer can rent a hotel room for 120 caps from Vera Weatherly or her robot . After purchasing the hotel room , the player character can access it for free thereafter . This room comes with a bed , which grants the Well Rested bonus effect of + 10 % experience . If the player character didn ' t rent the room , they can pick the ( Very Hard ) lock without losing Karma . Even though the bed inside is called " My Bed , " the player character can ' t use it until they ' ve rented the room . When the player character gets to the upper deck of the carrier , they can get a look at the aircraft that still remain . These are the same fighter jet s that are used in the " " add - on and were apparently the standard jet aircraft for the U . S military in 2077 . The exterior doors in the bridge tower lead to catwalks on the outside of the tower , most of which have either an ammunition box or a first aid box . The broken bow of the ship was separated from the main carrier hull and half - flooded . The lower levels are inhabited by mirelurks or mirelurk hunters ( depending on player character level ) , while the upper levels contain Pinkerton ' s laboratory and home . Pinkerton has set up numerous traps throughout the bow , such as rigged shotguns , frag mines , a gas leak and a rigged terminal placed conveniently near the heavy door to Pinkerton ' s lab .
