In our previous post we referenced the canal that cuts through the Isthmus of Corinth connecting the Ionian Sea with the Aegean Sea. In ancient times there was a paved road that stretched across the isthmus, called the diolkos, which enabled cargo and smaller ships to be hauled overland, thus avoiding the dangerous circumnavigation of the Peloponnese.
Our photo shows a portion of the western end of the diolkos. To the right and out of view, the canal runs parallel.
The BAS has this information re: this site in their collection, The Biblical World in Pictures commenting on their photo taken in the same area as mine above:
In Paul’s day a stone-paved sledway, called the Diolkos, was used to haul ships and their cargoes across the isthmus. At both ends of the road the pavement continued down beneath the waterline, allowing the shallow-draft ships to be floated onto and off of the sleds. The sleds were then pulled out of the water and across the isthmus by mule-power.
This view of the Diolkos is near the western end, looking beyond to the Gulf of Corinth (and the mountains along its northern coast sheltering the oracle shrine of Apollo at Delphi). At the right can be seen the western outlet of the modern canal. The stone pavement of the Diolkos clearly shows the ruts formed by sled runners over centuries of use. Corinth, of course, controlled the Diolkos traffic. Moreover, since ship crews and passengers using this route had to leave their vessels temporarily at Corinth anyway, they had less reason to make an additional port-call at Athens’ harbor on the Piraeus. Thus, many more travelers of the Roman era passed through Corinth than through Athens.
The diolkos was paved with hard limestone.
