Gemiler Island is covered with Lycian ruins, still containing some mosaics and leftovers of Byzantian churches. This island is also known as St. Nicolas island and is one of the places Christianity started to spread from. Letoon is located between Kas and Fethiye, about 4 km south of Xanthos and was another important religious centre of the Lycian region.

Letton was dedicated to the three national deities of Lycia – Leto, Apollo and Artemis. During archeological studies leftovers of churches have been found belonging to the early Christian era. Tlos, near Antalya, has been one of the most important religious centers of the Lycian region. According to the myth, the hero Bellerophon and his winged flying horse Pegasus used to live there. Tlos dates back to the time before 2000 B.C.

The graveyard, located on the natural rocks of the city acropolis, was filled with most elaborate house-type tombs of Lycia. The king-type tomb in the necropolis is dedicated to Bellerophon.
