Diolkos

The Diolkos [Greek meaning “haul across”] was a paved “road” that connected the Corinthian and Saronic gulfs before the Corinthian Canal was dug. It was built because sailing around the southern tip of the Peloponnese was very treacherous. Strabo, for example, writes ‘But when you sail around Cape Malea, forget your home” (= “you’ll never return!”; viii 6, 20)
