Vignazza Tower is a coastal watchtower in Giardini Naxos with a quadrangular structure, three stories high. It was constructed in 1544 to patrol Cape Schisò and the coast south of Port Schisò against the raids of the Barbary corsairs who were led by the Turkish corsair Barbarossa Kheir-ed-Din to attack and plunder the small fishing villages on the coast. When an enemy ship was sighted, the guardian of the watchtower sent out smoke signals to alert the villagers and other watchtowers of the imminent threat. There were many watchtowers such as Vignazza constructed along the Sicilian coast.
Vignazza Tower is located in the Recanati area of Giardini Naxos and is annexed to the archeological park. Its interior is occasionally used for exhibitions and performances.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
