What's NEW at CMMC?
A Special Exhibit For Summer 2017...
“Breaking Barriers"

During World War II, over 1,000 young American women left their homes and families to serve America as military pilots. Though the Army classified them as “civilians”, the Women Airforce Service Pilots (WASP) carried out dangerous missions, flying America’s most advanced military aircraft. A new exhibition at the Marconi-RCA Wireless Museum titled, “Breaking Barriers - Women Airforce Service Pilots of WWII”, will tell their story – the story of the first women to fly for the U.S. military.

The public is always invited to walk the grounds of the Marconi-RCA National Register District and experience the outdoor Antenna Field Trail exhibit at any time.

The Marconi-RCA National Register District is a 13 acre site that complements the modest, finely crafted buildings, built in 1914, common in the early 20th century. Full exterior Historic Restoration of all 10 buildings on the site had been completed by the Town of Chatham in 2008. Interior renovations, including full ADA compliance, were completed by CMMC, in the Operating Building, ("Marconi-RCA Wireless Museum") in 2010 and the former Hotel Nautilus ("Education Center") in 2014, Recent exterior renovations by the Town of Chatham added ADA access and landscaping.
