Pigeon valley is situated between Göreme and Uçhisar and is ideal for walking, as the trek is relatively easy. The name comes from the thousands of pigeon houses that have been carved into the soft tuff since ancient times. Although they can be found throughout Cappadocia, they are especially numerous in this valley. They were carved wherever space allowed, including abandoned cave houses and churches. In Cappadocia, pigeons have long been a source of food and fertilizer. The advent of chemical fertilizers has reduced the use of pigeon dung. However, some farmers still maintain their lofts because they insist that the reputation of Cappadocian fruits as the sweetest and most succulent in Turkey is entirely due to pigeon dung.
