Standing 170 meters tall in Manhattan's Tribeca neighborhood, 33 Thomas Street is a striking windowless skyscraper designed by John Carl Warnecke in the Brutalist architectural style. Originally built as the AT&T Long Lines Building, it functioned as a telephone exchange housing three major 4ESS switches for long-distance calling services and other competitive carrier switches. The fortress-like structure, located on Church Street between Thomas and Worth streets, has been reported to serve as a National Security Agency mass surveillance facility.
