Rosenstein Palace was built between 1822 and 1830 by the court builder Giovanni Salucci (1769–1845) in the classical style for King Wilhelm I. The palace stands in Rosenstein Park on a height overlooking the Neckar river valley. Formerly called the Kahlenstein (literally 'bald rock', because it was bare of trees), the hill was renamed Rosenstein ('rose rock'), and a rose garden was planted to the south-east of the palace.
Today, Schloss Rosenstein houses that part of State Museum of Natural History Stuttgart dealing with extant lifeforms.
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.
