The Ihlara Valley is a deep canyon, cut into the rock by the small river Melendiz Suyu. Inside is a lot of greenery. The walls of the valley contain many cave churches, chapels and monastries. Some of them with colourful wallpaintings of different styles. One of the best preserved chapels is the Agacalti Kilisesi (church under the tree) with paintings in the local Cappadocian style.
