Gamburg Castle was built in the mid-12th century by arcbishops of Mainz. Unlike many other castles, Gamburg was indeed renovated several times, such as during the Renaissance, but it was never destroyed and was continuously inhabited. Even during the Peasants' War, it remained intact thanks to the personal intervention of Götz von Berlichingen, making it one of the few castles to do so.
At the center of the castle complex with an almost oval layout stands the Romanesque keep. Surrounding the inner courtyard are the former stables, the so-called Forester's House, and the opposite 'castle,' consisting of the chapel tower, the great hall (Palas), the Middle Building, and the Rear Building, which has housed a chapel since 1921. The inner castle was surrounded by a fortification with six semicircular shell towers, a round corner tower, an outer gate with two round towers, and the moat later transformed into a baroque castle park.
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.
