At the corner of Suq al-Silah Street is a ruined domed structure. This is the gate to the palace of Manjak al-Yusufi al-Silahdar (the 'swordbearer' or 'armorer') - the same Manjak whose funerary complex is in the Bab al-Wazir cemetery. The gate was built at the beginning of his career, and his blazon with the sword of office is a prominent decoration. The shallow dome is also interesting as an example of a pure pendentive system. The collar of red stones in a zigzag pattern below the interior dome is striking. This gate was at the edge of Suq al-Silah, the Armorers' Bazaar, whose location near the Citadel was a logical consequence of its strategic importance and of the number of Mamluks quartered in the fortress. The trade of metalworking continues in this area today.
