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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
