The cathedral of Vaison was built on the ruins of a Roman temple, the remains of which can be seen outside the chevet. More than one church has existed on this site; a 6th-century basilica was destroyed by Frankish invaders.
The present building dates primarily from the 11th and 12th centuries. After a dispute with the Count of Toulouse in the late 12th century, the medieval city of Vaison was mostly abandoned for the new town. Today, little remains of the extensive medieval city except for the cathedral.
The apse is the most interesting aspect of the interior. Behind a simple stone altar, on a lower level than the nave, is the medieval bishop's throne and three semicircular benches for the canons. In front of the throne is an old sarcophagus containing the relics of St. Quenin (d. 578). The apse also contains several tomb niches of various styles and some reliquaries and statues.
The cloister, dating primarily from the mid-12th century, is a peaceful space with a lush central garden. The canons' buildings, such as the refectory and dormitory, have disappeared and many of the capitals were restored in the 19th century, but the cloister retains its medieval appearance and atmosphere. Most of the capitals are carved with foliage and vines, but some have charming creatures and human faces.
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.
