Lower Agora (Roman Period), Ancient City of Xanthos, Kinik Village, Kas, Antalya.
The Letoon, sometimes Latinized as Letoum, was a sanctuary of Leto near the ancient city Xanthos in Lycia. It was one of the most important religious centres in the region.
Xanthos was the name of a city in ancient Lycia, the site of present-day Kinik, Antalya Province, Turkey, and of the river on which the city is situated. The ruins of Xanthus are on the south slopes of a hill, the ancient acropolis, located on the northern outskirts of the modern city, on the left bank of the Xanthus, which flows beneath the hill.
