UNESCO of the world: Ephesus (Turkey)

Located within what was once the estuary of the River Kaystros, Ephesus comprises successive Hellenistic and Roman settlements founded on new locations, which followed the coastline as it retreated westward. Excavations have revealed grand monuments of the Roman Imperial period including the Library of Celsus and the Great Theatre. Little remains of the famous Temple of Artemis, one of the “Seven Wonders of the World,” which drew pilgrims from all around the Mediterranean. Since the 5^th century, the House of the Virgin Mary, a domed cruciform chapel seven kilometres from Ephesus, became a major place of Christian pilgrimage. The Ancient City of Ephesus is an outstanding example of a Roman port city, with sea channel and harbour basin.

UNESCO of the world: Historic Areas of Istanbul (Turkey)

With its strategic location on the Bosphorus peninsula between the Balkans and Anatolia, the Black Sea and the Mediterranean, Istanbul has been associated with major political, religious and artistic events for more than 2,000 years. Its masterpieces include the ancient Hippodrome of Constantine, the 6th-century Hagia Sophia and the 16th-century Süleymaniye Mosque, all now under threat from population pressure, industrial pollution and uncontrolled urbanization.

UNESCO of the world: Göreme National Park and the Rock Sites of Cappadocia (Turkey)

In a spectacular landscape, entirely sculpted by erosion, the Göreme valley and its surroundings contain rock-hewn sanctuaries that provide unique evidence of Byzantine art in the post-Iconoclastic period. Dwellings, troglodyte villages and underground towns – the remains of a traditional human habitat dating back to the 4th century – can also be seen there.

UNESCO of the world: Archaeological Site of Troy (Turkey)

Troy, with its 4,000 years of history, is one of the most famous archaeological sites in the world. The first excavations at the site were undertaken by the famous archaeologist Heinrich Schliemann in 1870. In scientific terms, its extensive remains are the most significant demonstration of the first contact between the civilizations of Anatolia and the Mediterranean world. Moreover, the siege of Troy by Spartan and Achaean warriors from Greece in the 13th or 12th century B.C., immortalized by Homer in the Iliad, has inspired great creative artists throughout the world ever since.

UNESCO of the world: Xanthos-Letoon (Turkey)

This site, which was the capital of Lycia, illustrates the blending of Lycian traditions and Hellenic influence, especially in its funerary art. The epigraphic inscriptions are crucial for our understanding of the history of the Lycian people and their Indo-European language.

UNESCO of the world: Hierapolis-Pamukkale (Turkey)

Deriving from springs in a cliff almost 200 m high overlooking the plain, calcite-laden waters have created at Pamukkale (Cotton Palace) an unreal landscape, made up of mineral forests, petrified waterfalls and a series of terraced basins. At the end of the 2nd century B.C. the dynasty of the Attalids, the kings of Pergamon, established the thermal spa of Hierapolis. The ruins of the baths, temples and other Greek monuments can be seen at the site.

UNESCO of the world: Selimiye Mosque and its Social Complex (Turkey)

The square Mosque with its single great dome and four slender minarets, dominates the skyline of the former Ottoman capital of Edirne. Sinan, the most famous of Ottoman architects in the 16th century, considered the complex, which includes madrasas (Islamic schools), a covered market, clock house, outer courtyard and library, to be his best work. The interior decoration using Iznik tiles from the peak period of their production testifies to an art form that remains unsurpassed in this material. The complex is considered to be the most harmonious expression ever achieved of the Ottoman külliye, a group of buildings constructed around a mosque and managed as a single institution.

UNESCO of the world: Nemrut Dağ (Turkey)

The mausoleum of Antiochus I (69–34 B.C.), who reigned over Commagene, a kingdom founded north of Syria and the Euphrates after the breakup of Alexander's empire, is one of the most ambitious constructions of the Hellenistic period. The syncretism of its pantheon, and the lineage of its kings, which can be traced back through two sets of legends, Greek and Persian, is evidence of the dual origin of this kingdom's culture.

UNESCO of the world: City of Safranbolu

From the 13th century to the advent of the railway in the early 20th century, Safranbolu was an important caravan station on the main East–West trade route. The Old Mosque, Old Bath and Süleyman Pasha Medrese were built in 1322. During its apogee in the 17th century, Safranbolu's architecture influenced urban development throughout much of the Ottoman Empire.
