The archaeological site at Agrigento, in Sicily, was inserted into the UNESCO World Heritage List in 1997. The remains from the Hellenic city, and additionally from the successive Punic-Roman era, the imposing Doric temples – to this day almost completely intact – the agora, the pagan and Christian necropolises, and the crawling network of subterranean acqueducts, constitute the richness of this site. Extending over approximately 1,300 hectares, it recounts a millenary history that began in the 6th Century B.C. with the foundation of the ancient Greek colony of Akragas.
