At the foot of the trail stands the Marconi/RCA receiving station complex, listed on the National Register of Historic Places and significant for its engineering, its architecture, and its long and distinguished role in the history of wireless communication. Its original ten buildings remain architecturally unchanged, making the site a rare example of an early wireless station. An early blueprint shows two 1914 Marconi horizontal antennas, and six X symbols mark the steel tubular masts built to support a mile-long receiving antenna. A dash-dot-dash line in the middle of the blueprint marks a balancing aerial, or antenna, supported by six steel lattice towers and designed to keep strong signals from the Marion transmitter from interfering with weak signals coming from Norway. Three of the lattice towers remain on the site, one near the road in front of the operating building and two across the road. Beyond the pitch pines and oak trees lies Stillwater Pond, one of Chatham’s kettle ponds, formed as the Laurentine ice sheet retreated 12,000 years ago.
