It was occupied by Mohammed Aziz Bouattour, the Prime Minister of Tunisia from 1882 to 1907 and grandfather of Muhammad al-Tahir ibn Ashur. He bequeathed the house to the latter before it returned to Mohamed Fadhel Ben Achour.

The house was acquired in 1970 by the municipality of Tunis. After a restoration, it is transformed in 1983 into a library whose mission is to collect and preserve historical documents related to the city of Tunis and Tunisians. In 1990, it also became the headquarters of the Tunisian Association of Monuments and Sites.
