Nemrut Dagi was discovered in 1881, but excavation didn't start until 1953.

The site was constructed by Antiochus 1, who prided himself on his royalty and power. He was deposed in 38 BC by the Romans after a 26 year reign. Antiochus believed himself to be the descendent of Apollo so, he built a statue of himself along with those of Apollo, Zeus, Tyche (Fortuna) and Hercules flanked by a lion and an eagle. An artificial mountain peak of rock 50 meters high is piled between the two ledges of the gods, and some suspect Antiochus' tomb may be underneath it.
The colossal heads of the ancient gods now lie scattered at the summit of the mountains making an impressive picture at sunset.

Mount Nemrut (2150 m above sea level) is Commagene's sacred mountain located in the middle of Taurus Mountains in Southeastern Turkey in the province of Adiyaman. One of the tourist attractions of Malatya is the 94 km road to Mt. Nemrut from the city center via Puturge and Tepehan.
The piece of land around the city of Adiyaman in south-eastern Anatolia was called Commagene in Greek and Roman times. The origin of the word is not known and thought to have been derived from " Kummuhu" which was the name of a kingdom that existed in this area during the Assyrian period in about the nineth century BC.
The region became a part of the Persian empire in the 6th century BC. The persian rule lasted until the defeat of Darius III by Alexander the Great at the battle of Issus (333 BC) . However, after his unexpected death in 323 BC, his empire was shared among his generals and the lands of Commagene fell to Seleucus I Nikator (305-280) who founded his kingdom at Antioch.
Commagene was set up as an independent kingdom at the beginning of the first century B.C. by Mithradates I Kallinikos. The Kingdom flourished in the reign of his son, Antiochos I Epiphanes ( 62 - 32 BC ). The Commagenian Dynastry lasted until AD 72, when their land was annexed by the Roman emperor Vespasian to the province of Syria.
The hierothesion (sacred last resting place) built by Antiochos I sits on top of Mt Nemrut . It consists of a tumulus and three terraces. The tumulus was created by heaping up the fist-size pieces of stone which were left over when the statues on two of the terraces were sculpted. The tumulus is 50 m high and 150 m. in diameter. Although the inscriptions at the back of the thrones on east and west terraces record that Antiochos I had chosen the hierothesion as his sacred last resting place or a place where his body will sleep for endless eternity, sysmic research did not show any grave chamber or large cavity in the tumulus.
The three terraces of the hierothesion, hewn from the living rock, occupy the east, west and north sides of the tumulus. The east and west terraces are similar and each consists of a row of statues and three rows of reliefs. The statues and reliefs on both terraces were almost identical. In addition to the statues and reliefs the east terrace has a large altar of offerings measuring about 13.5 x 13.5 m. The presence of altar indicates that the most important ceremonies took place on this terrace. This altar was used for offering gods plenty of incense, sweet-smelling herbs, roots and for glorious sacrifices. Traces of stairs to climb up the terraces and also to reach the back of the statues to read the cult inscriptions can be distinguished. The north terrace does not have statues or reliefs.
The colossal statues represent Antiochos I, the goddess Commagene, Apollon, Zeus and Heracles. Lion and eagle statues were used as the guardians of the hierothesion. Their average height is 8- 10 m. These are made of stone, too heavy and large to be carried to the muesum and remain where they were originally erected. Time has inflicted heavy damage on the sculptures- their bodies sit with their beautifully carved heads at their feet.
The reliefs which show the ancestors of Antiochos I are incomplete. Scholars believe that the hierothesion was not finished during the life of Antiochos I and was left as it was after his death. The reliefs on the western terrace show Antiochus I, shaking hands with the gods.
The best time to visit Nemrut is at dawn in order to watch the sun rise. The view is really unique, while the moon sets behind, the sun rises creating a fascinating colour harmony. The beauty of the monumental sculptures as well as the splendour of the scenery are unrivalled. The site is considered as the 8th wonder of the world.
