It is one of the most curious, the most astonishing monuments, not only of the island of Djerba, but of all the ancient architectural heritage of Tunisia.
Seen from afar, in its Djerbian “countryside”, it presents the appearance of the harmony of the religious buildings of the island. Closer up, we are surprised by the arrangements and the “disarticulation” of an ensemble from which nevertheless emanates a transcendence that captivates the visitor.
The monument, dating from the 14th century, is made up of three subsets:
• a prayer hall rising in the middle of a fenced yard, the floor of which is covered with lime plaster;
• interior outbuildings comprising a main room which housed Koranic teaching flanked by two small rooms, one for accommodation, the other for keeping food reserves;
• external outbuildings including a room for ritual ablutions and a Koranic school, which are also used as an underground grain mill and bakery!
The prayer hall, massive, with a squat minaret, and the exterior walls of which have been consolidated by buttresses, betrays military concerns: it is because the Fadhloun mosque belonged to a chain of mosques not far from the coast and which represented a second line of defense in the event of an enemy attack.
