Vorau Priory was founded in 1163 by Margrave Ottokar III. The monastery quickly became an religious and cultural center of Eastern Styria, but it was badly damaged by fires in 1237 and 1384. Vorau was located on the border to Hungary and therefore repeatedly faced military threats. The monastery was fortified and armed in the 1450s to defend the local population. The monastery was rebuilt into the Baroque style in 17th and 18th centuries. The fortifications were demolished and moat filled in 1844.
Vorau monastery was again damaged by fire in 1945 during the World War II. Today it is a conference center and parish church. There is also a notable library containing 40 000 volumes, including 415 manuscripts.
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.
