The largest dome of the mosque is known as the "Dome of the Eagle" (Qubbat an-Nisr) and located atop the center of the prayer hall. The original wooden dome was replaced by one built of stone following the 1893 CE fire. It is supported by the central interior arcade and has openings along its parameter.
It receives its name because it is thought to resemble an eagle, with the dome itself being the eagle's head while the eastern and western flanks of the prayer hall represent the wings. With a height of 36 meters (118 ft), the dome rests on an octagonal substructure with two arched windows on each of its sides.
