The city of Palmyra in Eastern Syria is the latest site in the ancient and classical world in the Middle East to come under threat from so-called Islamic State forces.
Palmyra is in the middle of the Syrian desert, in the north-east of Damascus and contains the monumental ruins of a great city that was one of the most important cultural centres of the ancient world.
From the 1st to the 2nd century, the art and architecture of Palmyra, standing at the crossroads of several civilizations, married Graeco-Roman techniques with local traditions and Persian influences representing the epic relics of a shared human history and were of particularly special meaning to Iraqis and said to the cradle of civilization.
