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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
