The Umayyad Mosque complex, which dates mostly from the 12th century, suffered extensive damage in October as both sides fought to control the walled compound in the heart of the old city. The fighting left the mosque burned, scarred by bullets and trashed. Two weeks earlier, the nearby medieval covered market, or souk, was gutted by a fire sparked by fighting.
With thousands of years of written history, Syria is home to archaeological treasures that date back to biblical times, including the desert oasis of Palmyra, a cultural center of the ancient world. The nation's capital, Damascus, is one of the oldest continually inhabited cities in the world.
At least five of Syria's six World Heritage sites have been damaged in the fighting, according to UNESCO, the U.N.'s cultural agency. Looters have broken into one of the world's best-preserved Crusader castles, Crac des Chevaliers, and ruins in the ancient city of Palmyra were damaged. Both rebel and regime forces have set up bases in some of Syria's significant historic sites, including citadels and Turkish bath houses, while thieves have stolen artifacts from museums.
