Oberkapfenberg is mentioned in a document for the first time in 1173. The current castle was erected around 1264. It was the residence and administrative seat of the Counts of Stubenberg and the seat of the regional High Court for most of the Mürz Valley. Around 1550 it was converted into a Renaissance fortress that was abandoned in 1739 and fell into disrepair. After 1955 the Stubenberg Family rebuilt their ancestral fortress within the old walls and adapted it into a castle hotel. Today Burg Oberkapfenberg is a cultural and culinary attraction of more than regional importance.
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.
