Burg Metternich was mentioned in documents first time 1268, when it was owned by Johann von Braunshorn. It is thought the castle is even older, with some historians indicating 1129 as the year of construction. Until the first half of 17th century, the castle was owned by Counts von Nassau-Dillenburg.
The castle was not damaged badly before 1689, when French army destroyed the castle during the Nine Years' War. It was never completely rebuilt.
The last member of the family to own the castle was Klemens von Metternich, one of the most famous diplomats of the Austrian Empire – he was foreign minister from 1809 to 1848.
Today there is a hotel and restaurant.
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.
