Brandenbourg Castle history goes back to the 9th and 10th centuries when there was a wooden fort on the site. The 13th century keep, now 11.9 metres high, used to have four floors, only three of which remain. In the 14th century a chapel was added to the castle. And during the 15th and 16th centuries the castle was expanded and a bailey, two towers, vaulted cellars and curtain walls were added. In 1668, the French attacked the castle which subsequently fell increasingly into ruin.
The castle was inhabited until the middle of the 18th century. Like many other medieval castles, it was then abandoned and left to fall into ruin. In 1936 and during the 1950s, the State carried out basic consolidation work. Since the 1980s, all necessary consolidation work has been performed while archaeologists have continued to explore the site for further evidence of the castle's history.
The castle is located high above the crossroads of the road from the River Sûre up into the Ardennes and that from Bourscheid to Vianden. The site, measuring 35 by 95 metres, consists of the main castle and of a lower courtyard. The site used to be fully accessible to the public but access is now restricted, probably in the interests of preventing further damage.
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.
