Wiedersberg Castle was built around 1200 to protect the route from Plauen to Hof. The first documentary evidence dates from 1267. The castle is considered the ancestral home of the barons Wiedersperger. The castle was expanded after 1300 and fell into disrepair from 1500. In the 16th century, a mansion in the Renaissance style was built in the valley in the local area. Today the ring wall and gate tower remain, as well as some vaulted cellars and the surrounding walls. The double neck ditch carved into the rock and the gate drive of the gate tower, which swings around 90 degrees in the tower, are remarkable.
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.
