Giardino della Kolymbethra
A citrus garden hiding a 2,500-year-old public works project — the Kolymbethra (Valle dei Templi, Agrigento; FAI since 1999) is a 5-hectare garden of lemon and orange trees planted in a narrow valley below the temples of Akragas, on the site of an enormous artificial lake (480 BCE) built by Carthaginian prisoners and later used as a fish pond, bird trap, and nymphaeum before silting up in the medieval period.

Key facts
- The Kolymbethra basin and Carthaginian prisoner labour (how the Greek tyrant Theron built the most ambitious artificial lake in ancient Sicily): the name Kolymbethra (from Greek κολυμβήθρα = swimming pool, basin, reservoir) refers to an artificial lake created by Theron, tyrant of Akragas (Agrigento), in 480 BCE using the forced labour of Carthaginian prisoners captured after the Battle of Himera (480 BCE: the battle was fought simultaneously with the Battle of Salamis, and ancient sources (Diodorus Siculus) suggest a coordinated Persian-Carthaginian strategy against Greece — Carthage attacking Sicily while Persia attacked mainland Greece; Theron and Gelo of Syracuse defeated the Carthaginians, capturing 20,000 prisoners; Theron assigned these prisoners to public works; the Kolymbethra basin, the Temple of Olympian Zeus (the largest Doric temple ever attempted), and the water supply system of Akragas were all built using this prisoner labour; the Kolymbethra measured approximately 2,000m × 1,000m and was up to 30m deep — the largest artificial reservoir in the Greek world at the time of its construction; it was fed by tunnels carved through the valley ridge and served as: a water reserve for the city; a fish farm (eels, mullets, and other Mediterranean fish); a bird hunting ground (the water attracted migratory birds which were netted for food); the lake began to silt up in the Roman period and was completely drained by the medieval period (approximately 9th–10th century CE Arab occupation period)

Practical information
