While walking through the medieval streets of the historic center, try to imagine the look of it a few centuries ago. It was protected by a large wall, surrounded by a moat, to strengthen the village core. The walls were restored and enhanced in the Sixteenth Century, during the Venetian domination. Today we can only see a long stretch of the remaining wall overlooking Piazza Garibaldi, incorporated in the Marquis' Palace. Near the sea, on the eastern side of Lama Monachile, stands a watchtower and defense, the last examples of a system of angular towers built along the fortifications, which rendered the city impregnable, as defined by the documents of the time.
