The Fortezza del Tocco is a fort in Acireale. It was built in the 16th century to defend the city from attacks by pirates.
After the Battle of Lepanto in 1571, the Barbary pirates continued to raid the Sicilian coastline. In 1582, Uluç Ali attempted to raid Acireale. Although the raid was unsuccessful, the population were afraid of further attacks and began fortifying the area.
The Spanish (then the rulers of the Kingdom of Sicily) built the Fortezza del Tocco between 1592 and 1616. The fort was designed by Camillo Camilliani and Vincenzo Geremia. Other nearby fortifications that were also built around the same time as the Fortezza del Tocco include the Torre Alessandrano, the Torre di Sant'Anna and the Garitta di S. Tecla.
Some modifications were made to the fort in the early 17th century. It repelled a French attack in 1675.
The fort lost its importance and was decommissioned in the 19th century. Its last guns were removed in 1834, and were taken to the Pinacoteca Zelantea de Acireale, where they remain today.
Since 1999, the fort and the surrounding area have been a nature reserve. It is open to the public.
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.
