Vault 120

Vault 120 is a Vault-Tec control vault situated in the ruins of New York City. It currently serves as the main communications base of the Republic of New York.

History
Vault 120 was first commissioned in 2062 under Project Safehouse, a plan to build nuclear shelters for US citizens in case there was a nuclear war. Vault 120 was unique in that it was a control vault, meaning that unlike most other vaults, it was designed to function the way it was advertised in Vault-Tec advertising. This vault was one of 5 to be planned for New York City

On the day of the Great War, Vault 120 sealed shut and didn't open for another 50 years, and when it did, the inhabitants used their G.E.C.K. to recolonize part of New York City above the entrance for the vault. This community was called Freetown and quickly rose to be one of the most influential settlements in the New York ruins.

Vault 120 still had a purpose as it was used to monitor radio signals and was also used for communications purposes. The vault also held a large percentage of the people living in Freetown, but mostly the upper-class residents. Later on, in 2178 the residents of Freetown would band together with other smaller settlements to form the Republic of New York. Vault 120 quickly became the main communications base for the nation and civilians were prohibited from living in the vault.

By 2287 the vault is still operational unlike most other vaults in the wasteland and still has a permanent population, although civilians have been prohibited from living in the vault due to it being occupied by military forces of the Republic of New York.

Layout
Unlike most other vaults, Vault 120 had a surprisingly large and open atrium area like Vault 76, except much bigger. It was also bigger in size than most vaults, with more spacious living and recreational areas for the dwellers to explore.
