Cairo - El-Azhar Mosque Main Liwan

The Main Liwan or Sanctuary on the southeast side of the court, with 140 marble columns (100 of them antique) and an area of almost 3,600 sq. yd/3,000 sq. m, is the principal lecture hall. The lower front half, with four much restored rows of arcading, is part of the original building; the higher rear part, with two prayer niches, was added by Abd el-Rahman.
