Henneburg Castle lies on a hill on the right bank of the Main River in the town of Stadtprozelten. Schenken von Klingenberg family built it as a border fortification around 1200. It was the residence of the Teutonic Order for almost 200 years and last served as the official residence of the noble Mainz Amtskeller officials.
It was deserted in the 16th century andfell into disrepair over time. The castle grounds are broken down into the upper castle, consisting of a fortification and main castle, as well as the outdoor grounds with moat and rampart and the defensive wall on the Main river side. The fortifications surrounding the upper castle, several castle gates, seven wall towers or their remains, both Great Hall ruins, the large and small keep and the roughly 150 metre long underground wall-walk accessible through exits in the wall towers, which links the south-west gateway to the northern part of the castle remain intact.
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.
