Falkenstein castle was originally built by the Bishop Tuto of Regensburg before 1074. The medieval stone castle was built in the early 13th century. It was expanded and rebuilt several times before the castle was burned down by the Swedes in 1634 (during Thirty Years' War). The decayed Falkenstein castle was restored in the 20th century. Today the castle is a museum, festival venue and restaurant.
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.
