The Citadel of Aleppo or Alep, by Unknown Artist, 13th Century. Syria, Jabal Saman, Aleppo, Aleppo. View entrance gate tower and bridge of Aleppo Alep. The Gate of Aleppo was defended by a pair of imposing towers crowned by a number of embrasures, at the end of the daring entrance bridge. The bridge was defended by the towers ever since they were built, but they were all unified and banked in Mameluk Mameluke Mameluk times by adding a huge structure, which is well identifiable thanks to the two color insets around the windows.
