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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
