The Sippican Historical Society and Sippican Lands Trust will celebrate the 100th anniversary of Marion’s Marconi installation, once home to the world’s largest and most powerful wireless telegraph station, with events on Oct. 3 and 4.

The pioneering Marconi Wireless Telegraph Company built the Marion installation in 1914. It consisted of 14 towers, each standing more than 400 feet tall.

The station handled all trans-Atlantic radio traffic, communicating directly with another high-powered wireless plant in Norway.

At 7 p.m. on Friday, Oct. 3, Calvin Trowbridge, Jr., author of “Marconi: Father of Wireless, Grandfather of Radio, Great-Grandfather of the Cell Phone, The Story of the Race to Control Long-Distance Wireless” will speak in the Marion Music Hall.

Copies of Trowbridge’s book will be available for purchase, and attendees will have the opportunity to speak with the author.  The lecture is free. No reservations are required.

For more information, call 508-748-1116 or email: info@sippicanhistoricalsociety.org.

The Sippican Lands Trust will host a one-hour, guided tour of their “Radio Tower” property on Saturday, Oct. 4 at 11 a.m.

The trust purchased the property in 1986, and it is the actual site of the once-active Marconi wireless telegraph station. Resident and radio tower steward Richard Evans will lead participants through the trails and remnants of the property.

In case of rain, the tour will be held on Sunday, Oct. 5 at 11 a.m. The tour is also offered free of charge to the public, with no reservations required.

The radio tower trail is accessible from Benson Brook Road, past the Marion Transfer Station. Parking is available in that area, and participants should gather to the right, near the Lands Trust kiosk at the head of the trail.

A property map is available online at http://sippicanlandstrust.org/wp-content/uploads/radiotower.pdf  For more information on the guided tour, call 508-748-3080 or email: robinshields@sippicanlandstrust.org.
