Göreme Açık Hava Müzesi
The open-air museum is a UNESCO World Heritage Site thanks to its spectacular landscape and amazing collection of cave churches decorated with elaborate Byzantine frescoes that were once part of a monastic complex. Within the museum is the 11th-century Elmalı Kilise (Church with the Apple), which has wonderfully preserved frescoes of biblical scenes and portraits of saints. The Karanlık Church (Dark Church) was extensively restored by UNESCO, and vividly colorful scenes, dominated by deep blues, decorate the walls and domed ceiling; the painting of Christ Pantocrator on the dome is particularly impressive (entrance to the church is an extra €6). In the nearby kitchen/refectory, a huge dining table that could seat 50 is carved from the rock, and it's easy to imagine priests and members of the early Christian community here packing in for meals. The museum covers a large area with dozens of caves, nooks, and crannies to explore, almost all of them easily reachable on paved paths.
