"Alex sez, "A computer programmer found a Roman ruin near his home in Italy when he was playing around with Google Earth & Google Maps."The story was originally found at News at Nature.com, the Best in Science Journalism, a pretty interesting site.
His eye was caught by unusual 'rectangular shadows' nearby. Curious, he analysed the image further, and concluded that the lines must represent a buried structure of human origin. Eventually, he traced out what looked like the inner courtyards of a villa.
Mori, who describes the finding on his blog, Quellí Della Bassa, contacted archaeologists, including experts at the National Archaeological Museum of Parma. They confirmed the find. At first it was thought to be a Bronze Age village, but an inspection of the site turned up ceramic pieces that indicated it was a Roman villa."
