Constructed of rocks and stones, this square castle dates back to the 9th century, but was extensively restored in the 14th century as the seat of the city's governor, and adapted for storing firearms in the 16th century, and was under military use until the 19th century. Stroll around the walls of the kasbah for sweeping views of the city's intertwining lanes, or get some of the best views of Hammamet and enjoy a breathtaking panoramic view of the bay, or visit the kasbah's small museum with historical exhibits and some interesting Tunisian artifacts.
