An ancient city in western Turkey will showcase tombs and sarcophagi unearthed from one of the largest marble cities of the world. The ongoing excavations in the Stratonikeia ancient city in Yatağan, Muğla reveal new historical artifacts as part of the project launched by Turkey's Culture and Tourism Ministry on March 1. The project allows excavation works to be carried out incessantly for a 12-month period and supports the ongoing efforts with additional experts and personnel. Speaking to Anadolu Agency, Bilal Söğüt, head of the Stratonikeia excavations, said that many findings dating back to some 3,500 years ago were discovered in the ancient city, which hosted many historical civilizations. Also known as the 'city of gladiators,' the historical cite was important in the Hellenistic, Roman, Byzantium and Anatolian periods as well as the Ottoman and Turkish Republic eras. Söğüt said that the excavation team found a wall of a tomb and a sarcophagus belonging to Roman Era and the findings are taken under protection. 'We [with Muğla Museum] initiated a work to display the tomb and sarcophagi -- which can be carried from its place -- at the entrance of the city by the board decision,' he said, adding that there were samples that could go back to some 4,500 years ago.
