Zwernitz Castle was originally the hereditary seat of the Walpodes of Upper Franconia. The keep and the tithe barn made of rusticated ashlars are part of the original Romanesque complex built in 1200. In 1338 the castle came into the possession of the Hohenzollern family. Around two centuries later the half-timbered buildings of the lower castle were added. When the rock garden was laid out, it was designed to incorporate a view of the castle located on a natural elevation above it.
An interesting exhibition in the castle complex documents the history of Zwernitz Castle, its inhabitants, and Sanspareil. From the keep there is a magnificent panoramic view of the Franconian Switzerland Natural Park.
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.
