Delphi, Greece

Scientists were pretty sure that they knew about where the legendary city of Delphi from ancient Greece was located. However, there was a problem in their investigation. The city of Kastri was located right on it. No one was too excited about the idea of digging up the town, especially the residents. (It's noteworthy that this "arrangement" meant that no one could get at the ruins and take them home as souvenirs.)

Then fate played its hand. An earthquake came along - this seems to happen a lot in Southeastern Europe - in 1870, and more less destroyed much of the place. It took about 20 years, but eventually everyone involved agreed that the town should be moved about 250 meters. The French School at Athens funded the move.   

Let the digging begin. And slowly bur surely, the area revealed its secrets. The ruins had been buried under centuries of dirt, so it was a difficult process. But after lots of study, we have a good idea what the area was like back in the old days.

The Temple of Apollo was the centerpiece, but there are other buildings of historic value in the area. One I didn't see - no time for the good-sized walk - was the stadium, which is way up the hill. The Pythian Games were held there; they were second only to the Olympics in importance. As you'd guess, the entire area is a UNESCO World Heritage Site.
