 When the al-Aqsa Mosque was built, the old steps were blocked, and the eastern aisle lengthened so that new steps from its end would exit north of the Mosque, so essentially the exit on the Temple Mount moved eastwards somewhat.A small library known as the "Maktaba al-Khataniyya" was also established in the remains of the Fatimid era fortification tower, today entered through the western portal of the twin-gate.The Triple Gate was blocked in the 11th century.
