Žumberk Castle was probably built during the end of the 13th century, on a hilltop above the village, and was known under the German name Sunenberg. Its walls formed a pentagon and were surrounded by a deep moat, with a service yard was placed next to the castle. Later, a township grew up under the hill.
The first known owner of the castle and neighbouring villages was a robber knight; ownership of the castle changed many times afterwards. At the beginning of the 18th century, the castle was not inhabited, though during 1760–70 a physician lived there. The castle became desolate and was left to be a source of construction material.
During 1926–48 the castle was owned by the Club of Czech Tourists, and its structure was stabilized to prevent further destruction. Today the market town of Žumberk is responsible for its maintenance, and access to the castle is unlimited and free.
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.
