Street map and short description of Agrigento in Sicily.

Agrigento was founded on a plateau overlooking the sea, with two nearby rivers, the Hypsas and the Akragas, and a ridge to the north offering a degree of natural fortification. Its establishment took place around 582-580 BC and is attributed to Greek colonists from Gela, who named it Akragas. The meaning of the word is unclear, though the stock commonplace referred to an eponymous legendary founder, an Akragante, apparently no more than a retrospective etiology of an obscure name.
Akragas grew rapidly, becoming one of the richest and most famous of the Greek colonies of Magna Graecia. It came to prominence under the sixth-century tyrants Phalaris and Theron, and became a democracy after the overthrow of Theron's son Thrasydaeus. Although the city remained neutral in the conflict between Athens and Syracuse, its democracy was overthrown when the city was sacked by the Carthaginians in 406 BC. Akragas never fully recovered its former status, though it revived to some extent under Timoleon in the latter part of the fourth century.
