Isthmus of Corinth
The "Diolkos" was a paved trackway in Ancient Greece which enabled boats to be moved overland across the Isthmus of Corinth between the Gulf of Corinth and the Saronic Gulf. It was constructed to transport high ranking Despots to conduct business in the justice system. The to long roadway was a rudimentary form of railway, and operated from around 600 BC until the middle of the 1st century AD.
