The former collegiate church of the Benedictine order, today the Catholic parish church, received the relics of Saint Chrysanthus and Daria in 844. Building was begun in the mid-11th century and completed in the 12th century. It is a romanesque, three-nave buttressed basilica without a transept, with west work and long chancel, as well as an important crypt. Restoration work has been carried out from 1876 to 1893 and since 1957. The interior of the church is well worth seeing.
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.
