Ivrea Castle was built on behalf of Amadeus VI, Count of Savoy, in 1358. Ivrea was built to signify the dominance of the House of Savoy over the region. The castle has four towers erected on a plan flank. It is located next to a cathedral and a bishop's palace. The castle is mentioned in the work of Giosuè Carducci.
The most significant changes were recorded at the end of the 18th century, when the castle was transformed into a prison, first destined to State prisoners and then also to common prisoners. With the prison function, which it maintained untile the first half of the 20th century, the structure was subject to a series of additions and adaptations that naturally divided the courtyard into two parts and defined the external spaces, closed by high perimeter walls.
The first studies of the structure, including the historical origins, date back to the endo of the 19th century, important documental sources for this were contributed by Giuseppe Giacosa and Alfredo d’Andrade.
In 1979, almost ten years after dismission, the restorations were completed that demolished the structures from the 19th and 20th century and rediscovered the antique structures in the courtyard and moat areas.
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.
