I saw this and just thought it was pretty cool. I'm sure most of you've seen it; but for those who haven't, an Italian programmer found the remains of an ancient villa while looking around his home town. I believe this is the correct map. Funny thing is, it's about 3000 feet from a non-imaged area (well, for now, anyway).
Luca Mori, the programmer who stumbled upon this find, is starting up a new site, CyberArcheologist.net. Best of luck! Now, if only the US had something as cool... Actually, I'm wondering if they truly know what they've found, yet. The discovery was only made 5 days ago (Sept 14, 2005), from what I can tell. Either way, congrats Luca!
