Uçhisar Castle

Cappadocia is a historical region in Central Anatolia, largely in the Nevşehir, Kayseri, Aksaray, and Niğde Provinces in Turkey. The name was traditionally used in Christian sources throughout history and is still widely used as an international tourism concept to define a region of exceptional natural wonders, in particular characterized by fairy chimneys and a unique historical and cultural heritage.

A fairy chimney or hoodoo (also called a tent rock, and earth pyramid) is a tall, thin spire of rock that protrudes from the bottom of an arid drainage basin or badland. Hoodoos, which may range from 1.5–45 metres, typically consist of relatively soft rock topped by harder, less easily eroded stone that protects each column from the elements. They generally form within sedimentary rock and volcanic rock formations.

Hoodoos are a tourist attraction in the Cappadocia region of Turkey, where houses have been carved from these formations.
