From Bill Thayer and Jona Lendering at New at LacusCurtius & Livius:
2300 Ancient Sites on Google Earth
On several occasions I have blogged on the possibilities of Google
Earth and its online spin-off, Google Maps. My last blog on this topic
was a bit over half a year ago, when I had some 1700 items available. In
the meantime, I have added more than 550 ancient sites to my list, from
all quarters of the ancient world.
