The Castello Baradello is a military fortification located on a 430 m high hill next to the city of Como. The castle occupies the ancient site of Comum Oppidum, the original settlement of Como, dating from the 1st millennium BC. Later it was one of the last Byzantine strongholds in the area, surrendering to the Lombards in 588. The castle was restored during the War of the Lombard League, with the help of emperor Frederick Barbarossa (1158). Barbarossa officially donated it to the citizens of Como in 1178.
Napoleone della Torre died here in 1278, having been imprisoned here by Ottone Visconti after the Battle of Desio; his nephew Guido was able to escape in 1283, as well as his brothers Corrado and Enrico the following year. Azzone Visconti restored and enlarged the fortification after conquering Como in 1335, and built another castle, the Castello della Torre Rotonda ('Castle of the Round Tower', now lost) and a citadel.
In 1527, by order of emperor Charles V, the castle was dismantled, with the exception of the tower, to prevent it from falling in hands of the French troops that had invaded the duchy of Milan. After belonging to monks and then to private individuals, the castle was restored in 1971.
The most preserved element is a square tower. It once had Guelph-type merlons. The walls are of Byzantine origin (6th-7th century); these were later heightened and provided with Guelph merlons, while another external line of walls was added.
Also from the 6th century are the Chapel of St. Nicholas and quadrangular tower, which was used as the castellan's residence. Napoleone della Torre was buried in the Chapel of St. Nicholas.
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.
