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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
