The large complex of temples and tombs in Agrigento dates as far back as 500 BC and includes Sicily's best preserved Doric temple-Tempio di Concordia-one of the most perfect to survive anywhere. 

Along with it in the eastern group is the Tempio di Juno Lacinia, almost as large, and in the western group is Temple of the Olympian Zeus, the largest of them at 40 meters but toppled by an earthquake.

The circular Doric Tempio di Heracles, also in the western group, was destroyed by the Carthaginians and rebuilt by the Romans, only to be partially destroyed in an earthquake. The entire group is listed as a UNESCO World Heritage Site.
