811 Tenth Avenue, Nuclear-resistant skyscraper in Hell's Kitchen, United States.
The 370-foot-tall concrete structure occupies an entire block on Tenth Avenue between West 53rd and 54th Streets in Manhattan.
Built in 1964 by AT&T to house telephone switching equipment, this windowless building was designed to withstand nuclear attacks during Cold War tensions.
The building represents a shift in telecommunications infrastructure development, marking the introduction of large-scale data centers in urban environments.
Four 2000-kilowatt generators and three 20000-gallon fuel tanks ensure continuous operations during power interruptions to the electrical grid.
The National Security Agency used this facility after 1985 for surveillance programs, making it central to national security operations.
