In 1383, the Davensberg branch of the noble lords of Büren acquired a newly constructed castle from Archbishop Friedrich of Cologne as a fief. It was intended as an outpost in the Almetal and was to be jointly owned by the Davensberg and Cologne Archbishop.
In 1394, the Davensbergs pawned the castle to Johann von Scharfenberg, a branch of the Padberg family. Concurrently, the noble lords of Büren pawned their half of the castle and town of Alme to Hermann von Padberg. The redemption of the Ringelstein castle took place in 1399 by Berthold von Büren.
While often suggested to defend against the Padbergs, there is no evidence linking the pawning and redemption of Ringelstein and Alme castles for this purpose.
In 1458, the castle was granted as a fief to the Landgrave of Hesse. During the Thirty Years' War, Ringelstein became a venue for witch trials, with a judicial site and torture facilities. In 1631, 55 people were convicted and executed as witches within 30 days. After 1802, Ringelstein declined in significance and fell into ruin.
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.
