October 9, 2012. On our vacation we traveled from Centerville, where we stayed, to visit Provincetown. Along highway 6 we stopped at the Marconi Site at Wellfleet, MA.
At the edge of the Atlantic ocean was a pavilion at the very spot where Marconi set up his station that transmitted the first transatlantic radio message.
Looking for tall antennas, I was amazed by this graphic showing the significant beach erosion. Apparently in 1980 two of the original four antennas were still standing but by 2012 there was nothing left, not a base or a cable fixture, nothing. Today there is much sand dune grass holding back erosion, so the memorial pavilion should stay for a while.
This map and dateline shows progress and tests made at the site.
