Schloss Greifenstein is a castle in the mountainous Fraconian Switzerland region of Upper Franconia, Germany. Since 1691 Greifenstein, the 'stone stronghold' of Heiligenstadt round its walls, is the seat of the noble Schenk von Stauffenberg family. Greifenstein is a prominent feature of the modern tourist itinerary called the Burgenstraße.
The Gothic castle that was first noted in 1172 was ruined and pillaged during the Peasants' war of 1524-1525 and was subsequently rebuilt. Then Marquard Sebastian von Schenk von Stauffenberg, Prince-Bishopric of Bamberg, took possession and rebuilt Greifenstein in Baroque style from 1691 to 1693, under the direction of the Bavarian architect Leonhard Dientzenhofer; consequently, as a seat of the bishop it is sometimes called Greifenstein Palais, though the aofficial bishop's palace stood (and still stands) in Bamberg.
A comprehensive restoration was carried out by Otto Philipp Schenk, Graf von Stauffenberg, in 1975–77.
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.
