The Zelve Open-Air Museum, which once housed one of the largest communities in the region is an amazing cave town, honeycombed with dwellings, religious and secular chambers. Zelve is situated about 10 km out from Goreme on the Avanos road.

Here, the Christians and Muslims lived together in perfect harmony, until 1924. Then Christians had to leave the Valley because of the exchange of minorities between Greece and Turkey, and the Muslims were forced to evacuate the Valley in the 50's when life became dangerous due to risk of erosion.

They left the site to set up a modern village, a little further on, to which they gave the name Yeni Zelve (New Zelve).
