 Both the Double and Triple Gates of the Herodian time allowed access to the Temple Mount esplanade via a vestibule followed by underground vaulted ramps.They have both been blocked since the Middle Ages, and the underground access routes have been partially or fully reconstructed during the Umayyad and later reconstructions and repair work.The Double Gate was blocked by the construction of a medieval tower in front of it, probably during Fatimid era.
