Located in Cappadocia, Derinkuyu is notable for its large multi-level underground city, which is a major tourist attraction. The historical region of Cappadocia, where Derinkuyu is situated, contains several historical underground cities, carved out of a unique geological formation. They are not generally occupied. Over 200 underground cities at least two levels deep have been discovered in the area between Kayseri and Nevşehir, with around 40 of those having at least three levels. The troglodyte cities at Derinkuyu and Kaymaklı are two of the best examples of underground dwellings.[citation needed]
The geomorphology of the area lends itself to underground construction. The soil is generally dry, and the tuff rock typical of the area is easy to work.[4]
The city contained food stores, kitchens, stalls, churches, wine and oil presses, ventilation shafts, wells, and a religious school. The Derinkuyu underground city has at least eight levels constructed to a depth of 85 metres (279 ft) and could have sheltered thousands of people.[5][6]
History
The oldest written source about underground structures is the writings of Xenophon. In his Anabasis (circa 370 BCE), he writes that the people living in Anatolia had excavated their houses underground, living well in accommodations large enough for the family, domestic animals, and supplies of stored food.[7] The first two floors of the Derinkuyu Underground City have been dated to this early period.
From Byzantine times (4th century CE) through 1923 Derinkuyu was known by its Cappadocian Greek inhabitants as Malakopea (Greek: Μαλακοπέα).[8] The underground city was greatly expanded in the middle Byzantine period to serve as a refuge from the raids of the UmayyadArab and Abbasid armies, during the Arab–Byzantine wars (780-1180). The city continued to be used as protection from the Mongolian incursions of Timur in the 14th century.[5][6] After the region fell to the Ottomans the cities were used as refuges (Greek: καταφύγια). As late as the 20th century the town's inhabitants, called Cappadocian Greeks, were still using the underground chambers to escape periodic waves of Ottoman persecution.[9]
The Cambridge linguist Dawkins, who spent time in the towns from 1910-1911 while writing his book on Cappadocian Greek, wrote:
"[T]heir use as places of refuge in time of danger is indicated by their name καταφύγια, and when the news came of the recent massacres at Adana [in 1909], a great part of the population at Axo took refuge in these underground chambers, and for some nights did not venture to sleep above ground."[10]

Its inhabitants were Cappadocian Greeks, who may have found a refuge here, perhaps from Roman, from Iconoclast, or later from Turkish and Mongol threats. Urgup itself was the Byzantine Prokopion; the Emperor Nicephoros Phocas is said to have passed this way, after his Cilician campaign; and the neighborhood was populous enough to support, at different times, a number of bishoprics.

"Anyone who attempts to find the Greek villages of Cappadocia today, either on the map or on the ground, is first faced by the problem that their names have been obliterated, a chauvinistic practice not only prevalent in modern Turkey, but practiced in Greece as well. Visitors to the so-called 'underground cities' at Kaymakli and Derinkuyu have difficulty in ascertaining that until 1923 they were called Anaku and Malakopi respectively (the latter being the Μαλακοπαία of Theophanes. Once located, however, these villages bear obvious traces of their Greek Christian past in the shape of sizable churches (some of which have been converted into mosques and are therefore well preserved, but with their frescoes covered with whitewash), and a number of rather elegant houses, whose Greekness is betrayed only by the initials and dates (usually about ten years before the 1923 exchange of populations."

The area became an important frontier province during the 7th century when Arab raids on the Byzantine Empire began. By now the soft tufa had been tunneled and chambered to provide underground cities where a settled if cautious life could continue during difficult times. When the Byzantines re-established secure control between the 7th and 11th centuries, the troglodyte population surfaced, now carving their churches into rock faces and cliffs in the Goreme and Sogamli areas, giving Cappadocia its fame today. […] At any rate here they flourished, their churches remarkable for being cut into the rock, but interesting especially for their paintings, relatively well preserved, rich in coloring, and with an emotional intensity lacking in the formalism of Constantinople; this is one of the few places where paintings from the pre-iconoclastic period have survived. Icons continued to be painted after the Seljuk conquest of the area in the 11th century, and the Ottoman conquest did not interfere with the Christian practices in Cappadocia, where the countryside remained largely Greek, with some Armenians. But decline set in and Goreme, Ihlara and Soganli lost their early importance. The Greeks finally ending their long history here with the mass exchange of populations between Turkey and Greece in 1923.
^Rodley, Lyn (2010). Cave Monasteries of Byzantine Cappadocia. Cambridge University Press. p. 1. ISBN978-0-521-15477-2. The tenth-century historian Leo the Deacon records a journey to Cappadocia made by Nikephoros Phokas shortly before he became emperor. Perhaps to recapture the attention of readers beginning to tire of troop movements he also offers a scrap of information about a curiosity of the region to which the emperor was heading: its inhabitants were once called troglodytes, because 'they went underground in holes, clefts and labyrinths, as it were in dens and burrows'. This brief note was probably not based on first-hand knowledge but it might have been prompted by an awareness of the vast number of rock-cut cavities in an area to the west and southwest of Kaisareia (Kayseri of modern Turkey). Had Leo been more inclined to garrulous digression (or perhaps just better informed), he might have supplied more details of the troglodyte region and the task of bringing scholarly order to the hundreds of rock-cut monuments and other cavities in the area might have been much similar. … At this time the region was still inhabited by a mixed population of Turkish-speaking Moslems and Greek-speaking Christians. The latter group left for Greece in the early 1920s, during an exchange of population of minorities that was part of the radical social re-ordering initiated by Kemal Atatürk; they were replaced by Turks from Greece, mostly from Thrace. In the two decades before this upheaval, however, members of the local Greek population acted as guides to Guillaume de Jerphanion, who made several visits to the volcanic valleys and wrote his meticulous descriptions of many painted Byzantine rock-cut churches.
