fire. 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 , the dome rests on an octagonal substructure with two arched windows on each of its sides. It is supported by the central interior arcade and has openings along its parameter. Courtyard In the courtyard (sahn), the level of the stone pavement had become uneven over time due to several repairs throughout the mosque's history. Recent work on the courtyard has restored it to its consistent Umayyad-era levels. Arcades (riwaq) surround the courtyard supported by alternating stone columns and piers. There is one pier in between every two columns. Because the northern part of the courtyard had been destroyed in an earthquake in 1759, the arcade is not consistent; when the northern wall was rebuilt the columns that were supporting it were not. The courtyard and its arcades contain the largest preserved remnants of the mosque's Umayyad-era mosaic decoration. Several domed pavilions stand in the courtyard. The Dome of the Treasury is an octagonal structure decorated with mosaics, standing on eight Roman columns in the western part of the courtyard. Its 8th-century mosaics were largely remade in the late 20th-century restoration. In a mirror position on the other side of the courtyard is the Dome of the Clock, another octagonal domed pavilion. Near the middle of the courtyard, sheltering an ablutions fountain at ground level, is a rectangular pavilion which is a modern reconstruction of a late Ottoman pavilion. Minarets Within the Umayyad Mosque complex are three minarets. The Minaret of Isa on the southeast corner, the Minaret of Qaytbay (also called Madhanat al-Gharbiyya) on the southwest corner, and the Minaret of the Bride located along the northern wall. Minaret of the Bride The Minaret of the Bride was the first one built and is located on the mosque's northern wall. The exact year of the minaret's original construction is unknown. The bottom part of the minaret most likely dates back to the Abbasid era in the 9th century. While it is possible that the Umayyads built it, there is no indication that a minaret on the northern wall was a part of al-Walid I's initial concept. Al-Muqaddasi visited the minaret in 985 when Damascus was under Abbasid control and described it
