UNESCO Says Syria's Cultural Heritage Being Devastated

The rubble of the minaret of Aleppo's ancient Umayyad Mosque, located in the UNESCO-listed Old City of the northern Syrian city, after it was blown up on April 24, 2013. The iconic mosque in Aleppo's labyrinthine Old City has been a key battleground since July 2012, with rebels seeking the ouster of Bashar al-Assad's regime laying siege twice but each time managing only to keep control for less than 48 hours.

An ancient village in northwest Syria. The Dead Cities, or Forgotten Cities, are a group of 700 abandoned settlements in northwest Syria between Aleppo and Idlib. Around 40 villages grouped in eight archaeological parks situated in northwestern Syria provide insight into rural life in Late Antiquity and during the Byzantine period. Most villages that date from the first to seventh centuries were abandoned between the eighth and 10th centuries.
