Myra, Turkey - The ancient town of Myra in the Lycia region of Anatolia, modern day Turkey, boasts a number of breathtaking ruins including the Acropolis on the Demre-plateau, the Roman theatre and Roman baths.
Maybe over time, and after many rains, a stream was rerouted through the old temple ruins. It would probably be where the Impions would get their drinking water from to. It would be pretty convenient since they live in the ruins.
