The Vatican Gardens have been a place of quiet and meditation for the popes since 1279 when Nicholas III moved his residence back to the Vatican from the Lateran Palace. Within the new walls, which he had built to protect his residence, he planted an orchard (pomerium), a lawn (pratellum) and a garden (viridarium).
Created around the hill of Saint Egidio (where the Palazzetto del Belvedere is located today) and the courtyards of the Vatican Museums, this was to be the first garden in the Vatican. However, should you visit the Vatican Gardens today you would begin by viewing a totally different area from that first orchard, one located in a more recent addition to what is now Vatican City State. It is there that larger and more recent gardens have been planted, covering together with the original garden about half of the 44 hectares of Vatican City.
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.
