Great Mosque of Raqqa
Raqqa, Syria
The Great Mosque of Raqqa (al-Jāmiʿ al-Kabīr fi ar-Raqqah) or Al-Qadim Mosque (Masjid al-Qadīm) is the oldest mosque, currently in a ruinous state, in Raqqa, Syria, located at the northern section of the city's heart. The mosque was built by the Abbasids in 772 CE, under the reign of caliph al-Mansur. All that remains of the mosque today are the baked brick minaret (25 meters (82 ft)) and the prayer hall (haram) façade with eleven arches that were added by Nur ad-Din Zangi during the 1165 CE renovation of the mosque. There used to be a small shrine in the center attributed to Wabisa ibn Ma'bad al-Asadi.
