Built on the remains of a Roman Arx during the Lombard era, the Caiazzo Castle was owned by notable figures like Count Theodoric of Caiazzo (9th century) and Count Landone (1034). Later, it fell under Norman rule and was fortified by Roger II with permanent garrisons.
In 1229, during the Hohenstaufen period, Caiazzo was besieged by John of Brienne but was freed by Emperor Frederick II, who stayed at the castle. Under the Angevins, it changed hands multiple times, eventually belonging to Lucrezia d'Alagno in 1461, who reinforced the walls against artillery fire.
In 1569, Matteo di Capua owned it, hosting poet Giovan Battista Marino. The Corsi family acquired it in 1607, followed by Giuseppe Andrea De Angelis in 1836, who heavily remodeled it, altering its medieval appearance.
The quadrangular castle sits atop a hill overlooking Caiazzo and the Volturno Valley. It has four towers: three round limestone ones and the square Torre di Lucrezia, named after Lucrezia d'Alagno. This tower includes multiple residential levels with vaulted ceilings and large windows, ending with a defensive rooftop.
The castle has two entrances, one near Torre di Lucrezia and another at the end of an old moat. The lower level retains its medieval service rooms with ogival arches, while a staircase leads to the 12th-century church of Santa Maria al Castello and the remodeled 19th-century residential quarters.
Nearby, remnants of Samnite polygonal walls from the 4th century BCE can be seen.
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.
