Al-Jazzar is also noted for his works of construction. He stripped the sites of Caesarea, of Athlit and of Ashkelon of their columns and their stones to restore the harbor of Akko, to reinforce its walls, to erect a mosque on the vestiges of the Crusader's Saint Croix cathedral and the monastery of the Knights of Saint John, to build baths and to open caravaneries,such as the Khan al-Umdan or the Inn of the Columns and the Khan al-Firanji or the Free Inn, which Volney described as follows:

These inns (...) are composed of four wings extending out from a square courtyard that serves as a garden. The lodgings are cells with nothing more than four walls, dust and sometimes scorpions. The innkeeper of the khan is responsible for providing the key and a mat: the traveler must provide the rest: as such, he must carry his bed, cooking utensils and even some of his own provisions for often no bread can be found in the villages.

Volney, A Voyage to Egypt and Syria

Al-Jazzar again rebuilds the Roman aqueduct that would bring the water from the Kabri sources to the city and builds a citadel. In 1799, its reinforced walls withstand Bonaparte's canons that strike the gates of the city for two months. The British fleet, which controls the sea, backs up Al-Jazzar. The plague ravages the French ranks, which are, in addition, confronted by the armed troops that occupy the Galilee. From then on, Bonaparte can only dream about a victorious withdrawal. On May 20th, the French will escape during the night. At the time, the Jews represented a quarter of the city's population, united under the authority of Hayyim Farhi who must have known the sad fate described by Oliphant.

In 1832, the Egyptians take possession of the city. In 1840, it is bombed and recaptured by the Turks. As soon as the prohibition to build outside the city walls is revoked, a new neighborhood is established. But they will soon abandon its irreparably silted harbor for that of Haifa. Under the British mandate, the citadel of Al-Jazzar, in which the Turks confined the founder of the Bahai sect, Baha Ullah (1868 - 1892), is converted into a prison. Hundreds of members of the Jewish resistance are imprisoned there together with non-political prisoners.
