Great Mosque of al-Mansur

When the Moroccan scholar and explorer, Ibn Battutah visited the city in 1327, he reported the mosque as still standing, but it disappeared at a later, unknown date; no trace of it survives today.

Most of the latter were composed of several pieces, joined endwise with glue, and clamped with iron bolts; but five or six of them, near the minaret, were formed from a single large tree-trunk each.

[9] Caliph al-Mu'tadid (r. 892–902) objected to this state of affairs, and in 893 expanded the Great Mosque by tearing down part of the Palace of the Golden Gate.

The wall originally separating the two was left standing, but was now pierced by 17 arched gateways: 13 into the courtyard of the mosque, and four on the side aisles.

[10] Ahmad ibn Rustah described the mosque, following al-Mu'tadid's restoration, as a "fine structure of kiln-burnt bricks well mortared, which is covered by a roof of teak wood supported on columns of the same, the whole being ornamented with [tiles the colour of] lapislazuli.
