Aragonese Castle stands on a volcanic rocky islet that connects to the larger island of Ischia by a causeway (Ponte Aragonese).
The Aragonese Castle is the most impressive historical monument in Ischia, built by Hiero I of Syracuse in 474 BC. At the same time, two towers were built to control enemy fleets' movements. The rock was then occupied by Parthenopeans (the ancient inhabitants of Naples). In 326 BC the fortress was captured by Romans, and then again by the Parthenopeans. In 1441 Alfonso V of Aragon connected the rock to the island with a stone bridge instead of the prior wood bridge, and fortified the walls in order to defend the inhabitants against the raids of pirates.
Around 1700, about 2000 families lived on the islet, including a Poor Clares convent, an abbey of Basilian monks (of the Greek Orthodox Church), the bishop and the seminar, the prince with a military garrison. There were also thirteen churches. In 1809, the British troops laid siege to the island, then under the French command, and shelled it to almost complete destruction. In 1912, the Castle was sold to a private owner. Today the castle is the most visited monument of the island.
It is accessed through a tunnel with large openings which let the light enter. Along the tunnel there is a small chapel consecrated to John Joseph of the Cross (San Giovan Giuseppe della Croce), the patron saint of the island. A more comfortable access is also possible with a modern lift. After arriving outside, it is possible to visit the Church of the Immacolata and the Cathedral of Assunta. The first was built in 1737 on the location of a smaller chapel dedicated to Saint Francis, and closed after the suppression of Convents in 1806 as well as the nunnery of the Clarisses.
The Aragonese Castle of the Ischia is open all year round, every day of the week, from 9am till sunset.
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.
