Rabenstein Castle is the smallest medieval castle in Saxony. It is located in the Chemnitz suburb of Rabenstein and belongs to the Chemnitz Castle Hill Museum.
The hill castle Rabenstein was first mentioned in 1336 in a document from Louis IV, Holy Roman Emperor in which he promised it as a fief to his son-in-law Frederick II, Margrave of Meissen, in case the line of Waldenburg were to die out without male heirs.
At this time the castle was larger than the current. The castle walls consisted of a 180 m long wall, which enclosed an area of two hectares.
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.
