Wardenclyffe Tower (1901–1917) also known as the Tesla Tower, was an early wireless telecommunications tower designed by Nikola Tesla and intended for commercial trans-Atlantic wireless telephony, broadcasting, and to demonstrate the transmission of power without interconnecting wires. The core facility was not completed due to financial problems and was never fully operational.
The tower was named after James S. Warden, a western lawyer and banker who had purchased land for the endeavor in Shoreham, Long Island, about sixty miles from Manhattan. Here he built a resort community known as Wardenclyffe-On-Sound. Warden believed that with the implementation of Tesla's "world system" a "Radio City" would arise in the area. He offered Tesla 200 acres (81 ha) of land close to a railway line on which to build his wireless telecommunications tower and laboratory facility.
