Zeugma Mosaic Museum, in the town of Gaziantep, Turkey, is the biggest mosaic museum in the world, containing 1700 m2 of mosaics. It opened to the public on 9 September 2011.
The museum’s mosaics are focused on Zeugma, which is said to have been founded as Seleucia by Seleucus I Nicator, a general in Alexander the Great’s army.
The treasures, including the mosaics, remained relatively unknown until 2000 when artifacts appeared in museums and when plans for new dams on the Euphrates meant that much of Zeugma would be flooded. Many of the mosaics remain covered and teams of researchers continue to work on the project.
