The Marconi Wireless Receiving Station in Marshall, California, along with it's transmitting counterpart in Bolinas, provided a vital link in a vast plan by the Marconi Wireless Company of America, headquartered in New York City, to establish an around the world wireless communication system.

The opening of the Marshall/Bolinas Stations and Kahuku/Koko Head Stations, for the first time in history, made almost instant communication possible, not only between California and Hawaii, but also between Japan and Europe or South America.

The Marshall/Bolinas stations also provided Ship to Shore communications covering the Pacific Ocean which made ocean travel much safer.

The property originally contained a mile long receiving antenna, supported by seven steel towers. Each tower was approximately 270 feet tall and was set in a concrete base. Four heavy concrete anchors surrounded each tower to hold guy wires. The towers have been dismantled.

The surviving structures that contribute to the historic district are the powerhouse, the operating building, the hotel, and the cottages.

Over the years, the property has been developed from barren coast land into a parklike setting with a backdrop of a pine forest and other extensive landscaping.

Extracted from the NRHP nomination dated 9 June 1989.
