The library is located on Sidi Saber (Arabic: سيدي صابر) Street, where it occupies the basement of former Catholic school once operated by the Sisters of St. Joseph of the Apparition.

[1] After the closure of the Sisters of St. Joseph of the Apparition's school in 1999, the Archbishop of Tunis Fouad Twal entrusted father Francisco Donayre with the project of creating the library.

The library has over 50,000 volumes focused on comparative religion, Tunisian culture and the social sciences, from antiquity to present day.

A French organization called Partnership Between Mediterranean Cultures, located in Aurillac, France, supports the library.

The Tunisian Association of Cartagena cooperates regularly with the library to organize various social and cultural activities, and it has permanent contact with the Carthage Studies Center and the Institute of Arab Literature in Tunis.
