Letoon Sanctuary

Letoon, near Xanthos in southwestern Türkiye, was the federal sanctuary and principal cult centre of ancient Lycia. UNESCO describes it as a place where religious and political life converged: inscriptions found within the sanctuary show that decisions of Lycian ruling authorities were publicly proclaimed there.

The sacred precinct contains three temples dedicated to Leto, Artemis and Apollo. It also includes the remains of a monumental nymphaeum built around a water source that was considered sacred in antiquity. The famous trilingual inscription of 337 BCE, written in Lycian and Greek with an Aramaic summary, was found near the Temple of Apollo and is a key document for the languages and institutions of ancient Lycia.

Letoon and nearby Xanthos were jointly inscribed on the UNESCO World Heritage List in 1988. The sanctuary is no longer a living place of ancient worship, so Templestan treats its sacred status as archaeologically and historically documented heritage. The ancient belief that the water source was sacred is part of the recorded cultic landscape, not a modern healing claim.

Visitors encounter temple foundations, inscriptions and water architecture that together reveal how religion, identity and federal political life were intertwined in Lycian society.
