Remains of the impressive walls of ancient Palaiomanina – stretching some 1,650 meters in length – date from the 4th century, and are partitioned into sections. Squared and trapezoidal rocks characterize this wall, complete with a 2-meter wide gate called Avloporta, an arch and horizontal beams. Beyond the walls there are tombs, cyclopean walls, evidence of homes from the copper age, remains from Mycenaean times, vaulted tombs, water cisterns, geometric burial jar, box-shaped graves from the classical years and much more.
