important bridgehead toward the east, the city of Otranto was provided since the antiquity of defense systems and fortified works. The siege suffered by the city in 1067 seriously damaged the fortress that was repaired and reinforced a few years later at the behest of Roberto il Guiscardo. The reconstruction promoted in 1228 by Frederick II of Swabia instead remain evident traces of the tower of the median body cylindrical, incorporated in the bastion at the tip of the lance, and in curtain walls of the north-east. An analysis of the undergrounds suggests that the castle was set to a plant with a central core with quadrangular, scanned at the corners by cylindrical towers.
After the sack of Otranto In 1480, the year in which the whole South of Italy was the object of the Turkish attack, the castle had to be rebuilt, which he did Alfonso of Aragon, Duke of Calabria. At the end of the century, when the city was given as a pledge to the Venetians, the structure was further enhanced with the addition of artillery and mortars. The Aragonese phase there remain only a tower and part of the walls. The current appearance of the small fortress it owes to the Spanish viceroy, who made it a true masterpiece of military architecture. The two polygonal bastions added in 1578 on the side facing the sea, inglobarono the preexisting aragonese bastion.
Today the castle of Otranto has a pentagonal plan, surrounded by a large moat and punctuated by four towers, three circular in carparo and one with the tip directed toward the sea. On the fifth side, discovered, opens the drawbridge. The fortress otrantina inspired the first gothic novel of history, the castle of Otranto, written by Horace Walpole in 1764.
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.
