St. Nicholas Church, Demre
The burial church of the historical bishop behind Santa Claus, 45 km from Kaş.

Enough context, no spoilers
Why it matters
Built around AD 520, the basilica stands over the burial place of Nicholas, a 4th-century bishop of Myra who became the source of the Santa Claus legend. Active until 1923, it is now a museum. Russian Tsar Nicholas I funded a 19th-century restoration; a sarcophagus once thought to hold Nicholas's remains survives inside — his bones were moved to Bari, Italy in 1087.
What to know before you go
St. Nicholas Church sits in the modern town of Demre, on the site of ancient Myra, about 45 km and roughly 40–45 minutes' drive east of Kaş along the coastal D400. It is the church built over the burial place of the historical Nicholas, a 4th-century bishop whose legend became the basis for Santa Claus — a rare case of a Lycian-coast site with instant global name recognition well beyond Turkey specialists.
The building visitors see today is largely the 1862 restoration funded by Russian Tsar Nicholas I, layered onto an early Byzantine basilica founded around AD 520. Inside, faded frescoes narrate episodes from Nicholas's life, and a marble sarcophagus — long associated with his original burial, though his remains were taken to Bari, Italy in 1087 — remains on display.
Demre itself also holds a well-known Lycian rock-tomb necropolis and a Roman theatre, both near the church; if time allows, they are an easy add-on to the same stop.
