I’m an engineer. If there is a canal, dam, bridge, or whatever engineering marvel anywhere around, I have to see it. Luckily, our tour group had the Corinth Canal on the itinerary. The Roman Emperor Nero originally tried to build a canal to link the Aegean Sea with the Gulf of Corinth, but it was too difficult, so back then, they just dragged ships across the isthmus. I wouldn’t want to do the dragging. The Corinth Canal was started in 1881. No locks, just a canal, but wow, what a cut.
