The Temple of Concordia is one of the amazing temples in the valley; it is a temple of 430 B.C. from the ancient Greek city of Akagras. The Temple of Concordia has a quadrangular shape, a remarkable height of 13.481 meters and occupying a remarkable surface of 843.38 square meters.
A simple antechamber, equipped with two columns, prepared the entrance of the main cell, while a vestibule of important dimensions acted as treasurer. It was thanks to the historian Fazello that the temple bears this name because he found an inscription in Latin characters near the temple in honour of the Concordia degli Agrigentini.
