The Castello Normanno ('Norman Castle') in Paternò was built in 1072 by Count Roger I of Sicily to protect the Simeto valley from Islamic raids. The first nucleus of the fortress was soon enlarged, and it subsequently lost its original military functions. Under Henry VI it was made the seat of the Count of Paternò, assigned to his fellow Swabian Bartholomew of Luci. Later the castle housed kings and queens, such as Henry's son Emperor Frederick II, Eleanor of Anjou and Blanche I of Navarre, as the castle had been included in the so-called Camera Reginale estates ('Queen's Chamber') by King Frederick III of Sicily.
The Chamber was abolished in the 15th century, and in 1431 the castle was acquired by the Special family; until 1456 it was owned by the Moncada family. Used as a jail, in the following centuries it became increasingly decayed, until restoration work begun in the 19th century brought it back to its ancient prominence.
The castle has a rectangular plan, on three floors, with a height of 34 m. Originally, it had Ghibelline-style merlons, of which today only remains can be seen. Notable is the colour effect created by the dark shade of the stones and the frames of the Gothic-style mullioned windows, in white limestone.
The first-storey houses several service chambers and the Chapel of St. John, decorated with precious 13th-century frescoes. The piano nobile houses a large Weapons Hall. The king's residence was located in the upper floor.
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.
