Description & Facts: A little montage of our visit to the ruins of Corinth Greece. Corinth, or Korinth (Greek: Κόρινθος, Kórinthos) is a city in Greece. In antiquity it was a city-state, on the Isthmus of Corinth, the narrow stretch of land that joins the Peloponnesus to the mainland of Greece. To the west of the isthmus lies the Gulf of Corinth, to the east lies the Saronic Gulf. Corinth is about 48 miles (78 km) southwest of Athens. The isthmus, which was in ancient times traversed by hauling ships over the rocky ridge on sledges, is now cut by a canal.
