What was the name of Tesla's wireless transmission tower on Long Island?

Tesla’s wireless transmission tower on Long Island was called Wardenclyffe Tower. The project was built at Shoreham, near the north shore of Long Island, New York, as part of Tesla’s plan for worldwide wireless communication and electrical transmission.

Construction began in 1901 with financial support from J. P. Morgan. Architect Stanford White designed the distinctive wooden tower, while Tesla developed the electrical equipment beneath it. The facility was intended to send messages across the Atlantic, but Tesla’s ambitions expanded toward transmitting electrical power without wires.

The tower was associated with Tesla’s “World Wireless System.” He believed the Earth and atmosphere could help carry signals and energy over long distances. The project struggled because of rising costs, technical uncertainty, and competition from Guglielmo Marconi’s increasingly successful radio system. Morgan eventually declined to provide the additional funding Tesla wanted.

The tower was never completed as Tesla envisioned and ceased operation. It was dismantled for scrap during World War I in 1917. “Tesla Tower” is a descriptive nickname, but Wardenclyffe Tower is the project’s proper historical name; “Tesla Coil Tower” and “Magnifying Transmitter” refer to related ideas or equipment, not the tower’s official name.
