The Leonine City (Latin: Civitas Leonina) is the part of the city of Rome which, during the Middle Ages, was enclosed with the Leonine Wall, built by order of Pope Leo IV in the 9th century. [1]
This area was located on the opposite side of the Tiber from the seven hills of Rome, and had not been enclosed within the ancient city's Aurelian Walls, built between 271 and 275. After Christianity had risen to prominence and the Western Roman Empire had collapsed, the area had to be defended through the construction of a new wall, since it housed St. Peter's Basilica.
Nowadays, the territory of the former Leonine City is made up of Vatican City State and the Roman rione of Borgo.
The Leonine Wall, which defines Leonine City, was constructed by Pope Leo IV following the sacking by Muslim raiders of Old St. Peter's Basilica in 846. [2] Built from 848 to 852 as the only extension ever made to the walls of Rome, this three-kilometre wall completely encircled the Vatican Hill for the first time in its history. [3] An abortive start had been made by Leo III, but disturbances in the city had suspended work, and the Romans dismantled the sections that had been begun and used them in private constructions. [4] Pope Leo IV used his estate workers, inhabitants from the surrounding countryside, Saracens captured after the sea battle of Ostia in 849 and funding from an imperial Frankish donation, to construct the wall, which ran in an enclosing U-shape from the riverbank at Hadrian's Mausoleum, soon to be known as the Castel Sant'Angelo, up the slopes of the Vatican Hill encircling the basilica and descending again to the river. The walling was constructed of tuff and tiling, forty feet high, with 44 strong towers at bowshot intervals. The massive round corner tower that still crowns the Vatican hill has its origins in this construction campaign. [5]
Three new gates gave access to the newly enclosed Borgo. Two were in the stretch of wall that led back from the Castel Sant'Angelo: a small postern gate behind the fortified Mausoleum, called the Posterula S. Angeli and later, from its proximity to the Castello, the Porta Castelli, and a larger one, the principal gate through which emperors passed, near the church of St. Peregrino, called the Porta Peregrini, later the Porta S. Petri. [5] A third gate opened the Leonine City to the rione of Trastevere. A festival celebrated the official completion of the walling, 27 June 852. [6]
In addition, chain towers were built along the Tiber river to repel Saracen assaults by water. [7]
In 1083, after refusing to crown Henry IV as the next Holy Roman Emperor, Pope Gregory VII found himself under siege within the Leonine City. After Henry took the city, Gregory fled to Castel Sant'Angelo. Gregory attributed the loss of the Leonine City to famine and negligence and not so much to "the courage of Henry's men". [8]
Later, more extensive circumvallation was effected under Pope Pius IV (reigned 1559–1565), when Leo's walling was broken in places. Three further gates had been opened in the walls.
In 1870, when the military forces of the Kingdom of Italy captured Rome, overthrowing what was left of the Papal States, the Italian government intended to allow the Pope to keep the Leonine City as a small remnant Papal State. However, Pope Pius IX would not agree to that arrangement, and thus there was a 59-year standoff, when the Popes considered themselves "prisoners in the Vatican", [9] settled in 1929 by the Lateran Treaty, [10] which recognized the sovereignty and independence of Vatican City.
Year 848 (DCCCXLVIII) was a leap year starting on Sunday of the Julian calendar.
Pope Leo IV was the bishop of Rome and ruler of the Papal States from 10 April 847 to his death. He is remembered for repairing Roman churches that had been damaged during the Arab raid against Rome, and for building the Leonine Wall around Vatican Hill to protect the city. Pope Leo organized a league of Italian cities who fought and won the sea Battle of Ostia against the Saracens.
A prisoner in the Vatican or prisoner of the Vatican described the situation of the pope with respect to Italy during the period from the capture of Rome by the armed forces of the Kingdom of Italy on 20 September 1870 until the Lateran Treaty of 11 February 1929. Part of the process of Italian unification, the city's capture ended the millennium-old temporal rule of the popes over central Italy and allowed Rome to be designated the capital of the new nation. Although the Italians did not occupy the territories of Vatican Hill delimited by the Leonine walls and offered the creation of a city-state in the area, the popes from Pius IX to Pius XI refused the proposal and described themselves as prisoners of the new Italian state.
Saint Peter's Square is a large plaza located directly in front of St. Peter's Basilica in Vatican City, the papal enclave in Rome, directly west of the neighborhood (rione) of Borgo. Both the square and the basilica are named after Saint Peter, an apostle of Jesus whom Catholics consider to be the first Pope.
The Passetto di Borgo, or simply Passetto, is an elevated passage that links the Vatican City with the Castel Sant'Angelo. It is an approximately 800-metre-long (2,600 ft) corridor, located in the rione of Borgo. It was erected in 1277 by Pope Nicholas III, but parts of the wall were built by Totila during the Gothic War.
A rione of Rome is a traditional administrative division of the city of Rome. Rione is an Italian term used since the 14th century to name a district of a town. The term was born in Rome, originating from the administrative divisions of the city. The word comes from the Latin word regio, meaning "region"; during the Middle Ages the Latin word became rejones, from which rione comes. Currently, all the rioni are located in Municipio I of Rome.
Borgo is the 14th rione of Rome, Italy. It is identified by the initials R. XIV and is included within Municipio I.
Prati is the 22nd rione of Rome, identified by the initials R. XXII. It belongs to the Municipio I since 2013, while previously, along with Borgo and quartieri Trionfale and Della Vittoria, it was part of the Municipio XVII.
The Arab raid against Rome took place in 846. Muslim raiders plundered the outskirts of the city of Rome, sacking the basilicas of Old St Peter's and St Paul's-Outside-the-Walls, but were prevented from entering the city itself by the Aurelian Walls.
Via della Conciliazione is a street in the Rione of Borgo within Rome, Italy. Roughly 500 metres (1,600 ft) in length, it connects Saint Peter's Square to the Castel Sant'Angelo on the western bank of the Tiber River. The road was constructed between 1936 and 1950, and it is the primary access route to the Square. In addition to shops, it is bordered by a number of historical and religious buildings – including the Palazzo Torlonia, the Palazzo dei Penitenzieri and the Palazzo dei Convertendi, and the churches of Santa Maria in Traspontina and Santo Spirito in Sassia.
The Gardens of Vatican City, also informally known as the Vatican Gardens in Vatican City, are private urban gardens and parks which cover more than half of the country, located in the west of the territory and owned by the Pope. There are some buildings, such as Vatican Radio and the Governor's Palace, within the gardens.
