The Siege of Damascus (634) lasted from 21 August to 19 September 634 AD b[âº] before the city fell to the Rashidun Caliphate. Damascus was the first major city of the Byzantine (Roman) empire to fall in the Muslim conquest of Syria.
There has been concern over Syria's World Heritage Sites since the beginning of the conflict -- and in 2013, the World Heritage Committee placed all six Syrian sites on its  danger list  of places at risk of being irreparably damaged or lost forever.nly the ancient city of Damascus appears to have been spared. The U.S. missile strikes that began Monday night focused on northern and eastern Syria and included targets around the old city of Aleppo, which is a UNESCO-designated World Heritage Site, one of about 1,000 around the globe.
