The Arcadian Bridge, also known as bridge of Kazarma, is the Mycenaean bridge near the village Arkadiko.
It is considered as the oldest preserved bridge in Europe and the oldest single-arch bridge still in use today. The bridge was built by the Mycenaeans in the 13th or 14th century BC and was part of the road network. The bridge is made of giant boulders, characteristic of Mycenaean cyclopean structures. Its length is 22 meters, width 5.6 meters and a height of 4 meters. Apart from the Mycenaean bridge, four similar bridges survive in the region.
