 Bab Zuweila ( or Zuwayla ) is a medieval gate built in 1092 . It is the last remaining southern gate from the walls of Fatimid Cairo . The gate is today commonly called Bawabet El Metwalli . Its name comes from bab , meaning " door " , and Zuwayla , the name of a North African tribe . The towers are semi @-@ circular . Their inner flanks have lobed arches as decorations , a North African motif introduced to Egypt by the Fatimids . The vestibule to the right contains a half @-@ domed recess with elegantly carved arches at each corner . The gates were massive , weighing four tons . The gates today have two minarets , open to visitors , from which the area may be viewed . Additions were made during the 15th century .
