The Quirinal Palace is one of the three current official residences of the President of the Italian Republic. It is located on the Quirinal Hill, the highest of the seven hills of Rome. It has housed thirty Popes, four Kings of Italy and twelve presidents of the Italian Republic. The palace extends for an area of 110,500 square metres and is the ninth-largest palace in the world.
The current site of the palace has been in use since Roman times. During the reign of Constantine the last complex of Roman baths was built here. The Quirinal became a popular spot for the Roman patricians, who built their luxurious villas. An example of those are the remains of a villa in the Quirinal gardens, where a mosaic, part of the old floor has been found.
The current palace was built in 1583 by Pope Gregory XIII as a papal summer residence. The pope commissioned the architect Ottaviano Mascherino to build a palace with porticoed parallel wings and an internal court. The project was not fully completed due to the death of the pope in 1585 but it is still recognisable in the north part of the court, especially in the double loggia facade, topped by the panoramic Torre dei venti (tower of the winds) or Torrino. To the latter, a bell tower was added according to a project by Carlo Maderno and Francesco Borromini.
The Palace was also used as the location for papal conclaves in 1823, 1829, 1831, and 1846. It served as a papal residence and housed the central offices responsible for the civil government of the Papal States until 1870 when the Papal States were merged in the united Kingdom of Italy. The palace became the official royal residence of the Kings of Italy. The monarchy was abolished in 1946 and the Palace became the official residence and workplace for the Presidents of the Italian Republic.
The Quirinal Gardens, famous for their privileged position that makes of them almost an 'island' elevated on Rome, were over the centuries changed depending on the tastes and needs of the papal court.
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.
