| All traces of this mosque have disappeared. However,
descriptions of the mosque exist. In 754, al-Mansur became the
Abbasid Caliph, succeeding his brother Saffah as ruler. By 762
he commissioned the construction of a new eastern capital, choosing
Baghdad as his site. The new circular city was designed with
ash drawings onto the ground for al-Mansur to view prior to construction,
which began that same year. By its completion in 767 the Round
City measured 2000 meters in diameter. It featured four main
gates equally distant from each other: the southwest gate was
the Kufa Gate; the southeast was Basra; the Khurasan Gate extended
to the northeast and the Damascus Gate to the northwest. The
walls were constructed out of mud brick with reed supports, while
the domes and vaults were composed of baked brick. The main mosque
of the city (see diagram above) was about 100 meters by 200 meters
with columns used to support the ceiling around the edges of
the mosque. There was no mihrab, so one wall was used as the
qibla wall. This mosque clearly pointed to Mecca as did all Abbasid
mosques from now on. |
