The Castellamonte Castle is a medieval building situated on the hill overlooking the city. The earliest sources that document its presence dating back to 1066, but the structure had to be earlier. It became one of the most important fortified structures of Canavese under the descendants of Arduino, Marquis of Ivrea, then king of Italy: the wall surrounded the whole hill and was accessible by seven gates still visible.
The original castle, destroyed during the Tuchini Rebellion (1383-1387) that devastated the region, was rebuilt at the beginning of the fifteenth century. Of that era remain the tower-gate of the wall, the tower-door and the general structure, with four buildings arose around the access road. In the first half of the nineteenth century, the entire property went to the accounts of St. Martin of Sale and Castelnuovo; then move on to the accounts Ricardi of Netro.
The complex is now made up of four buildings, which are accessed through a Baroque portal that leads into the large square-garden, and various sections of the perimeter wall. The building to the right, 'White Palace', has a seventeenth century plant attributed to the architect Amedeo di Castellamonte; the left one, 'Red Tower' is the work of Luigi Formento, who turned it into a villa in neo-Gothic style.
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.
