Medersas are schools for study of the Quran. They declined in the late 19th century when broader education came into vogue. Fine examples - mostly still used as schools - are clustered around the Zaytouna Mosque. With an ornately studded door, the Medersa Mouradia was built in 1673 by Mourad II, son of Husseinite bey Ali Pasha, on the ruins of a Turkish barracks destroyed during a rebellion. It's used to train apprentices in traditional crafts.
