Europe's oldest village sought under Greek bay

Visitors walk on the deck of the MS Turanor PlanetSolar, the world's largest solar-powered boat, moored at Zea Harbor, in Athens, on Tuesday Aug. 5, 2014. The 35-meter (115-foot) vessel is in Greece to take part in a Swiss-Greek underwater archaeology project to seek traces of what could be one of the oldest human settlements in Europe, and shed new light on how the first farming communities spread through the continent.
