811 Tenth Avenue, also known as the AT&T Switching Center, is a significant 370-foot-tall skyscraper located in the Hell's Kitchen neighborhood of Manhattan, New York City. Designed by Kahn & Jacobs, the building was completed in 1964 and occupies the full block on 10th Avenue's western side between West 53rd and 54th Streets. This windowless structure was specifically designed to withstand a nuclear blast and was originally built to house telephone switching equipment for AT&T.
The building has been at the center of controversy, particularly due to its windowless design and its use by the National Security Agency for surveillance purposes under the Fairview program. In 2000, AT&T upgraded the facility from a hardened Telco data center to an AT&T Internet Data Center, reflecting its evolving role in telecommunications.
As of recent years, the building contains substantial backup systems, including four 2,000-kilowatt generators and three 20,000-gallon storage tanks for fuel oil, ensuring power during grid interruptions. Located in a historically commercial and working-class area, 811 Tenth Avenue remains a testament to the technological infrastructure of New York City.
