Dar Othman is one of the palaces of the medina of Tunis. The residence is located in the south of the medina, 16 El Mebazaâ Street. Dar Othman was built in the end of the sixteenth century (around 1595) by Othman, dey of Tunis, who reigned from 1593 to 1610. During the first half of the 19th century, Al-Husayn II ibn Mahmud transformed it into a provision's house to store supplies for soldiers staying in barracks of the neighborhood. Thus, the palace is also called Dar Al Oula (provision's house).
