Below the kasbah sits this enchanting 17th-century Sufi mausoleum, with a brilliantly tiled interior and narrow tower. The guardian, gorgeous Madame Zemourda, is a descendant of one of the occupants; call and she will arrive to open the door and show you around. Just outside is a bewitchingly pretty, tree-shaded square and cafe; ask there if you don't have a phone.
