The Temple of Heracles (or Hercules or il Tempio di Ercole) of Agrigento, Sicily’s Valley of the Temples possesses eight reconstructed, massive Doric-style columns. Built in the late 6th century BCE, it is considered the first temple to have been constructed of the seven that we know of at the Valley of the Temples. Valley of the Temples has been a UNESCO World Heritage Site since 1997.
