Xanthos was the capital city of the Lycian Federation and its greatest city for most of Lycian history. It was made famous to the Western world in the 19th century by its British discoverer Charles Fellows. It is very old – finds date back to the 8th century BC, but it is possible that the site may have existed during the Bronze Age or during the first centuries of the Iron Age.
Xanthos and Letoon are often seen as a “double-site”, since the two were closely linked and Letoon was administered by Xanthos. Letoon was the sacred cult center of Lycia, located less than 10 km to the south of Xanthos. Xanthos-Letoon is one of the most remarkable archaeological sites in Turkey. For this reason, it has been registered in the UNESCO World Heritage Sites list. Currently there is a French team excavating Xanthos and Letoon.
