One of the most important ruins of Telmessos, the Amynthas Rock Tombs are monumental tombs from the Lycian period. Built in the 4th century BC, these tombs were carved into the steep cliffs of Fethiye and were prepared for kings and nobles.

The most magnificent of the tombs is the Amynthas Tomb, which bears the inscription "Amyntou tou Hermagou" (belonging to Amynthas, son of Hermagios). With its high columns and temple-style architecture, it is considered one of the most impressive examples of the Lycian tomb tradition.
