On 8 August 1830, Hussein II Bey signed an act granting land for the purpose of honouring Louis IX "at the location of the prince's death [at] La Malka".
This act confirmed old treaties concluded between France and Tunisia.

On account of the political difficulties related to the abdication of Charles X and the death of Hussein II in 1835, the act did not enter into force until 1840, after the terms had been confirmed by Ahmed I Bey.
The location was chosen beforehand by the consular agent Jules de Lesseps, son of the consul general of France Mathieu de Lesseps: it is the site of the ancient Punic temple of Eshmoun on the Byrsa, which was renamed "Mount Louis-Philippe".

Thus, the first block of the building, designed by Germain Architects, was placed on the 25 August 1840, but work did not begin until 1841.
The chapel was consecrated on 25 August by Mgr Sutter.
The modest building designed to house the priest was not used for this purpose; it served as the original archaeological museum for the site.
