According to the inscription at the entrance of the mausoleum, the monument was built in the 17th century during the reign of the Muradid dynasty,[1] six centuries after the death of the saint Sidi Abu El Hassan El Lakhami in 1085.
The building kept receiving visitors for centuries until its closure by the Tunisian authorities in 2011, after the revolution.
Before the construction of Sidi Lakhmi mosque (also called El Jedid mosque), access to the mausoleum was through a small entrance in front of Bab Jebli and opens onto a small court.
The second, on the western side, is composed of two arches and leads to a small rectangular room.
It has a dome made of pottery tubes that help to reduce the total weight, and limestone corner blocks that ensure the transition from the square part of the basis to the circular one.
