Across northern Syria, rebels, soldiers and civilians are making use of the country's wealth of ancient and medieval antiquities to protect themselves from Syria's 2-year-old war. They are built of thick stone that has already withstood centuries and are often located in strategic locations overlooking towns and roads.
