This is the site where radar was invented in the 1930s ( in a resort town called Santa Marinella, near Rome).
On February 1, 1944, the Nazis rigged the almost five-hundred year old tower that was here and blew it up (the radio antenna that you see in the photo was construced on top of the old tower).
The Nazis blew up many landmarks along the coast (even in Ostia and Ladispoli, too), so that daylight precision bombers could not find their way.
I walked here today from the port of Rome, Civitavecchia. See this site for more information:
