Description | Syria / Aleppo / The entrance to the Citadel. One of the oldest continuously inhabited cities in the world, Aleppo preserves remnants of more than four millennia of Near Eastern history. The Citadel of Aleppo is a densely layered microcosm of this long and complex history. The majority of the structures on the citadel were erected by the Ayyubids in the 12th and 13th centuries, but substantial structures are also preserved from the Ottoman period (beginning in the 16th century) © Fausto Giaccone/Anzenberger/ASK Images |
