The construction of Gerione Castle was probably motivated by the need to control mountain routes and its strategic position as an observation point for a large part of the Sele plain. Documented for the first time in a parchment from 1056 during the Lombard period, the exact date of its construction is unknown.
With the Assise of Capua in 1220, the Gerione Castle was acquired by Frederick II of Sweden for the Demanio Regio, becoming directly dependent on the emperor and included among the Castra exempta, the main fortifications of the kingdom.
The structure maintained its military-defensive function until 1515 when, due to its inconvenient location for the needs of the time, it was handed over to the Collegiate Church of Santa Maria della Pace by the last feudal lord to possess it, Duke Ferdinando Orsini. According to others, the castle was used both as a prison and as a Spanish garrison during the feudal rule of the Grimaldi Princes of Monaco, Marquises of Campagna.
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.
