The
Round city of Baghdad was constructed by the
Abbasid Caliph Abu Ja’far al-Mansur during 762–768, surrounded by enclosures with four gates, namely Bab al-Kufa ("gate of
Kufa"), Bab al-Sham ("gate of
al-Sham or
Damascus"), Bab al-Khorasan ("gate of
Khorasan"), and Bab al-Basra ("gate of
Basra"). However, these four gates were eventually destroyed. Today the area is the neighborhood of
Karkh in
Mansour district, which located in southwest Baghdad. During the late Abbasid era, the 28th caliph,
al-Mustazhir, laid out a plan to expand the enclosure with additional walls, gates, moats and obstructions against invaders. The expansion plan was carried out during the reign of the succeeding Caliph
al-Mustarshid, and additional four gates were constructed, namely Bab al-Muadham, Bab ash-Sharqi, Bab al-Talsim and Bab al-Wastani. These four gates remained long after the fall of the Abbasid Caliphate. ==Gates==
