Rapture (also known as the North Atlantic project and the Rapture Colony) is a massive underwater city forged by the personal dreams of Andrew Ryan to escape from the political, social and religious anxieties of a post-World War II world. It was established on November 5, 1946 and finished in late 1951. Rapture lies at the bottom of the North Atlantic Ocean, as a gleaming metropolis of massive Art Deco-styled buildings, connected by networks of reinforced glass tunnels, bathysphere systems and submerged railways. It largely resembles the Manhattan borough of New York in both size as well as general appearance. The city is completely self-sustaining and all of its electricity, including pumping networks, water filtration, air purification and defense systems, are powered by the volcanic vents in Hephaestus. Fresh food and oxygen recycling are taken care of by large sections of man-made forest and farm centralized in the Arcadia zone, as well as fish along with other sea life from Neptune's Bounty. Transportation within Rapture is provided by Rapture Metro, a connected bathysphere system, which consists of spherical pressurized capsules, through which citizens could access most areas of the city. Part of Rapture Metro is the bathysphere inside the remote lighthouse in the North Atlantic, which is Rapture's only entrance from the outside world. Another mode of transportation within Rapture is the Atlantic Express, a pressurized rail system for moving a larger number of citizens (though this mode of transportation was decommissioned a long time ago). Other areas of Rapture are connected through bulkhead doors. Areas within some levels are connected by glass tunnels: smaller ones for pedestrians, larger ones for tramways of a rail system between areas. Rapture is intentionally isolated from the world and the only way to access it seems to be bathyspheres taken down from the lighthouse perched on an island above.........
