The French sacking of the city after the Siege of Jaffa in 1799 proved the inadequacy of the city walls, and when the city was returned to Ottoman control in 1800, Turkish and British engineers began to rebuild the fortifications. This task was completed under Abu-Nabbut from 1810 and onwards. Abu Nabbut added a monumental eastern gate crowned with three cupolas. The fortifications were specially designed to cope with European artillery and possessed thick walls, with substantial corner bastions, capable of supporting large cannons. Similar fortifications have survived at Acre. However, later in the nineteenth century the political situation had changed, and Abu-Nabbut's fortifications were no longer needed. By 1888 the dismantling process was complete and the moat was entirely filled in. Today, only two gateways and a short section of Abu-Nabbut's wall remains.
