The Benedictine Territorial Abbey of San Michele Arcangelo has been existed at least from 1078 and was probably built in the 5th century. The benedictine Abbey Church (12th century), dedicated to St. Michael, has a notable portal and a Norman-style bell tower with mullioned windows. The Norman lord Humphrey of Hauteville and his son Rudolph made large donations to the abbey. In 1484, after joining the Benedictine Congregation of St. Giustina from Padua, the abbey was enlarged and restored in Renaissance forms.
Afterwards it decayed due to numerous wars ravaging the country in those years. Renewed starting from 1590, it received a cylindrical cupola in 1650. The monks abandoned the abbey in 1784.
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.
