Aleppo is the largest city in Syria and the capital of Aleppo Governorate.
Aleppo is one of the oldest continuously inhabited cities in the world; it has been inhabited since perhaps as early as the 6th millennium BC.
The city's significance in history has been its location at the end of the Silk Road, which passed through central Asia and Mesopotamia.
Aleppo is characterized by mixed architectural styles, having been ruled, among the other, by Romans, Byzantines, Seljuqs, Mamluks and Ottomans.

The Citadel of Aleppo is a large medieval fortified palace in the centre of the old city of Aleppo, northern Syria. It is considered to be one of the oldest and largest castles in the world. Usage of the Citadel hill dates back at least to the middle of the 3rd millennium BC. Subsequently occupied by many civilizations including the Greeks, Byzantines, Ayyubids and Mamluks, the majority of the construction as it stands today is thought to originate from the Ayyubid period. - in: wikipedia
