Gutenburg Castle is the ruin of a hill castle above the village of Gutenberg in the county of Bad Kreuznach. The castle is first recorded in 1213 as castro Weitersheim. In 1334 the counts of Sponheim (Lower County of Sponheim) sold the castle, which had meanwhile been renamed the Gutenburg. After the sale it underwent a major conversion. Following the extinction of the House of Sponheim (the Kreuzenach line died out in 1414 and the Starkenburg line in 1437) the castle went to the Lower Sponheim lords (mainly the Margraviate of Baden and Electoral Palatinate). The castle lost its importance over time, was destroyed during the Thirty Years' War and fell into ruins. Today the castle ruins are in private ownership.
The castle consisted of an inner ward completely surrounded by a ring-shaped outer ward, protected by curtain walls with mural towers as well as a neck ditch. Considerable sections of the wall remain visible today.
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.
