Bärenfels castle, previously known as Steinegg, is located at the entrance to the Wehra valley above Wehr, high up In the Hotzenwald hill. It was built by Vasolt family in 1323-1330. In the 13th century the castle probably passed into the possession of the Barons of Schönau. Later, the ownership passed on to the Markgrafen (earls) von Hachberg They, in turn, let the castle to the Barons of Bärenfels, knights from Basel, after whom the castle is named today. Since the end of the 19th century the Schwarzwaldverein (Black Forest hiking club) has renovated the castle ruins and opened it for visitors. From the top of the tower, which is visible from afar, you can enjoy a great view of the Swiss Jura, the Dinkelberg and the Wiesental.
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.
