The Mausoleum of Sidi Sahab, generally known as the Mosque of the Barber, is actually a zaouia located inside the city walls. It was built by the Muradid Hammuda Pasha Bey (mausoleum, dome and court) and Murad II Bey (minaret and madrasa). In its present state, the monument dates from the 17th century.
The mosque is a veneration place for Abu Zama' al-Balaui, a companion of the prophet Muhammad, who, according to a legend, had saved for himself three hairs of Muhammad's beard, hence the edifice's name. The sepulchre place is accessed from a cloister-like court with richly decorated ceramics and stuccoes.
