The world's largest solar-powered boat, "MS Turanor PlanetSolar" sails through the Corinth Canal near the town of Corinth on July 28, 2014.  The boat arrived to Greece as part of a joint archaeological project focused on underwater exploration off one of Europe's oldest human occupation sites, the Franchthi cave in the Argolid, southeast Peloponnese. The project is taking place in one of Greece's richest archaelogical areas, the Argolid, known for its major palatial complexes in the Bronze Age that include Mycenae and Tiryns and later, classical-era city-states and sites like Argos and the ancient-theatre site of Epidaurus.
