The ancient site of Zeugma is situated on the banks of the Euphrates. It was an important city of the Kommagene Kingdom in the past. There was an ancient bridge of boats which was connecting the riverbanks in the ancient times, forming one of the major river crossings of the region. The most of the archaeological site is now lost under the waters of the Birecik Dam, but the open-air Museum in the site is still very moving and exciting place to visit those Roman residential mosaic remains. The most spectacular findings and mosaics are now displayed in the Zeugma Mosaic Museum in Gaziantep. Zeugma was founded by Seleucos I in the 4th century BC. He was one of the generals of Alexander the Great who fought for control over his empire after his death in 323 BC. In ancient times, the name Zeugma encircled the two cities, one was on western banks of the Euphrates and also known as Seleucia after the founder, while the other eastern settlement was called Apamea, since Seleucus’ wife was called Apama.
