Every great tomb has an author, and this one has a name you can hold on to. The mausoleum was founded under Ali Bey, the second bey of that name, the fourth ruler of the Husainid dynasty, who governed Tunisia between 1759 and 1782. He did not simply commission a grave. He commissioned a house for an entire line of rulers. Arabic sources say the work began around the year 1184 of the Hijri calendar, which corresponds to 1770, and that it was carried out under the supervision of Qasim al-Rassa', the sheikh of the city of Tunis, the official charged with the affairs of the capital. Building continued over several years and was completed around 1191 in the Hijri calendar, that is 1777. Some accounts date the foundation of the monument to 1777 itself, which fits neatly if you read that year as the moment the building was finished rather than the moment the first stone was laid. What makes this place unusual is that it never stopped growing. Instead of remaining the tomb of one man, it expanded generation after generation, and each expansion swallowed parts of the neighbouring houses. That is why you find yourself in a building that is less a single room than a small urban quarter turned inward, a family estate made of stone, stucco and silence.
