Xanthos or Xanthus, also referred to by scholars as Arna, its Lycian name, was an ancient city near the present-day village of Kınık, in Antalya Province, Turkey. The ruins are located on a hill on the left bank of the River Xanthos. The number and quality of the surviving tombs at Xanthos are a notable feature of the site, which, together with nearby Letoon, was declared to be a UNESCO World Heritage Site in 1988.
The city of Xanthos was a centre of culture and commerce for the Lycians, and later for the Persians, Greeks and Romans who in turn conquered the region. Xanthos influenced its neighbours architecturally; the Nereid Monument directly inspired the Mausoleum at Halicarnassus in the region of Caria.
