The Minarets
The most spectacular feature of the mosque are the minarets on either side of the facade, reminiscent of the propylon to a pharaonic temple.
Originally the two minarets stood independent of the brick walls at the corners. These are the earliest surviving minarets in the city and they have been restored at various times during their history. The massive salients were added in 1010 to strengthen their structure, and the northern minaret was incorporated into the city wall. Inside, these strange structures are hollow, for they have been built around the original minarets, which are connected with brackets and can still be seen from the minaret above.
