There are some interesting Islamic monuments around town. On the edge of the souq is the imposing Zaouia of Sidi Ibrahim (rue 2 Mars 1934), which contains the tomb of the 17th-century saint. On the other side of the road is the multi-domed Mosque of the Strangers (ave Abdelhamid el-Kadhi). The 18th-century Mosque of the Turks is north of the souq on place d'Algérie. Built in the same fortress style as the island's traditional mosques, the only clue to its Turkish origins is the distinctive Ottoman minaret. All of these monuments are closed to non-Muslims but can be admired from the courtyard outside.
