Yes, the U.S. government has built extensive underground facilities, some of which are described as being like "cities" due to their size and self-sufficiency.
During the Cold War, the U.S. government invested heavily in creating a network of hardened underground bunkers and command centers to ensure the continuation of government operations in the event of a nuclear attack.
One of the most well-known examples is the Raven Rock Mountain Complex in Pennsylvania, sometimes called the "Underground Pentagon". It was built to serve as an alternative headquarters for the Pentagon and can house thousands of government officials, equipped with its own power, water, air filtration, dining facilities, and even amenities like a post office and chapel.
Another example is the Mount Weather Emergency Operations Center in Virginia, a Continuity of Government facility operated by FEMA. It includes a hospital, crematorium, dining and recreation areas, sleeping quarters, water reservoirs, an emergency power plant, and even a radio and television studio.
A now declassified example is the Greenbrier Bunker, known as "Project Greek Island". This bunker, located beneath the Greenbrier Resort in West Virginia, was built to shelter the entire U.S. Congress during a nuclear attack. It remained secret for over 30 years until its existence was revealed by The Washington Post in 1992.
These facilities were part of the broader Continuity of Government (COG) plan, designed to maintain essential government functions during a major emergency.
