Schwarzenberg Castle was based on a medieval fortification and together with St. George's Church dominates the scene of the large county town of Schwarzenberg.
The castle was probably founded in the 12th century as a fort and was the original base for the settlement of Schwarzenberg and its vicinity. The former castle was given its present appearance by a conversion into a hunting lodge for the Electorate of Saxony from 1555 to 1558. In 1851-52 its keep and south wing were raised and, in 1875-76, an office building extension was added.
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.
