We found this old Roman footbridge on one of our many side-journeys while driving around the Peloponnese in Greece. It’s called the Arkadiko Bridge, and was built in Mycenaean times, approx 1300 BC. That’s over 3300 years ago, and it’s still standing (there are 4 such-brides in the Peloponnese. It is also one of the oldest arch bridges in the world, and is still in use! I wonder if the bridge-builders though that over 3000 years layer there would still be traffic over it.
