What is the oldest bridge in Europe?
This one! The Mycenaean bridge of Kazarma!
It was part of a military road, connecting Tiryns and Epidauros, built around 1,300–1,200 BCE by the Mycenaeans.
It is constructed from limestone boulders without binding material, the characteristic Cyclopean way of Mycenaeans, with a corbel arch. Still in use!
Another bridge of the same construction in the same area. In total, 5 of them are still standing!
