CMMC is again pleased to announce our Summer Science Courses for kids. We are offering six-one week courses this year on a variety of topics including astronomy, communications, robotics, chemistry, and marine environment. The courses will be held at the new STEM Education Center on our CMMC campus.

We are excited about this wonderful opportunity to engage our children during the summer. We hope you'll be able to take advantage of it. Space is limited so be sure to sign up early.

Last August we unveiled the preview of our upcoming 2014 exhibit titled "Tracking the Great White Shark." This CMMC exhibit will demonstrate the wireless and satellite technologies that are utilized in shark tracking. In our preparation of this exhibit, we gratefully acknowledge the support of Dr. Greg Skomal (MA Dept of Marine Fisheries) and OCEARCH. The official opening of this exhibit will be in Spring 2014 and housed in the Hotel Nautilus.

A sincere 'thank you' to all who visited us in 2013. Looking forward to this season, CMMC will be celebrating the 100th anniversary of the construction of the Marconi complex with special exhibits in the newly renovated Hotel Nautilus.

Also a special thanks to our dedicated volunteers who staffed the museum in 2013. We hope we can count on you again this year. As CMMC continues to grow, we look forward to welcoming more volunteers in 2014.

Renovation Nears Completion on Historic "Hotel Nautilus"
Hotel Nautilus

The renovation which began in the spring of 2013 has made great progress and will soon be nearing completion. The official opening will be in 2014 with the unveiling of new exhibits housed in the hotel space.

The building is commonly referred to as Hotel Nautilus from its days as a hotel while the rest of the Marconi complex was being completed in 1914. Later it was used by the early RCA staff and the Navy in WWII. The first floor will be converted into expanded exhibit space, education center, meeting space, archival space and administrative space.

restored Opns Bldg
The Marconi campus is a 13 acre site that complements the modest, finely crafted buildings common in the early 20th century. A full exterior and interior restoration and renovation was done in 2009-2010. Recent exterior renovations by the Town of Chatham added ADA access and landscaping.
