From about 1233 the Bamberg bishops had the Romanesque Griffen parish church enlarged and rebuilt as a Premonstratensian monastery. The first canons descended from Vessra Abbey in the Franconian County of Henneberg. The monastery complex was completed in 1272 and significantly enlarged by Baroque buildings in the 17th century. Griffen remained the only Premonstratensian abbey in the Inner Austrian lands until its abolition under the rule of Emperor Joseph II in 1786.
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.
