Schönburg Castle was first mentioned in history between the years 911 and 1166. From the 12th century, the Dukes of Schönburg ruled over the town of Oberwesel and had also the right to levy customs on the Rhine river. The most famous was Friedrich von Schönburg - a much-feared man known as “Marshall Schomberg” - who in the 17th century served as a colonel and as a general under the King of France in France and Portugal and later also for the Prussians and for William Prince of Orange in England.
The Schönburg line died out with the last heir, the son of Friedrich of Schönburg. The castle was burned down in 1689 by French soldiers during the Palatinate wars. It remained in ruins for 200 years until it was acquired by the German-American Rhinelander family who bought the castle from the town of Oberwesel in the late 19th century, and restored it.
The town council of Oberwesel acquired the castle back from the Rhinelander family in 1950. Since 1957 the Hüttl family have been living at the castle on a long-term lease; they operate a hotel and restaurant there.
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.
