Neugebäude Palace is a large Mannerist castle complex in the Simmering dictrict of Vienna, Austria. It was built from 1569 onwards at the behest of the Habsburg emperor Maximilian II on the alleged site of Sultan Suleiman's tent city during the 1529 Siege of Vienna and apparently modeled after it.
It fell into disuse already in the 17th century and today stands in ruins. Under monumental protection since the 1970s, there are various efforts to restore the site.
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.
