Bab Tuma

The Bab Tuma (English: Gate of Thomas) is the northeastern gate of the Old City of Damascus in Syria.

History
In 1191, this gate was the means by which the Assassin Altaïr Ibn-La'Ahad entered Damascus during his hunt for the Templar black arms merchant Tamir. As the Saracens guarding the gate would not have permitted the entry of an Assassin, Altaïr sneaked in by blending with a group of scholars. The scholars assisted Altaïr in gratitude for rescuing one of their own from the harassment of Saracen soldiers just moments earlier.

Altaïr returned to Damascus twice more through this gate that year when he was tasked to kill two other Templars, the Merchant King Abu'l Nuqoud and the scholar Jubair al Hakim.
