Minarets. The skyline of the Old City, and some other neighborhoods in East Jerusalem, is dotted with the tall, narrow stone structures of minarets, in various designs. The minarets are square, round or polygonal shaped, and topped by a balcony, from which the muezzin calls the believers, five times a day, to prayers. The most beautiful minarets were built by the Mamluks in the 13th -14th century, along the West and North façades of the Haram al-Sharif/Temple Mount.
