The Fethiye Museum is a compact, well-arranged museum in the town centre with an archaeological section and an ethnographic section. The star exhibit is the Trilingual Stele from the nearby sanctuary of Letoon — a 4th century BC inscription in Lycian, Greek, and Aramaic that was instrumental in deciphering the Lycian language.
Beyond the stele, the collection includes Lycian pottery, Roman-period statues, Byzantine jewellery, and artefacts from the surrounding ancient cities. The ethnographic section covers Ottoman-era life in the region. It is small enough to see in an hour and provides useful context before visiting the Lycian sites around Fethiye. Closed Mondays.
