Vatican

Vatican City, officially Vatican City State, is a small landlocked country within Rome, Italy. Home to under 500 residents, Vatican City is the smallest city-state in the world and is ruled by the Pope, the head of the Catholic Church. One named peak in the country, Mons Vaticanus, stands 83 m (272 ft) tall with 16 m (52 ft) of prominence.

Geography

Vatican City is an enclave within the city of Rome, Italy. This independent country spans just 49 hectares (121 acres) and has an estimated population of under 500 residents.

The miniature city-state lies on Vatican Hill. The geography of Vatican City centers around the major buildings of the Church, including St. Peter’s Basilica, the Sistine Chapel, the Vatican Museums, and the Apostolic Palace.

Walls surround much of the Vatican, and St. Peter’s Square is the main entrance into the country. A white line drawn across the square marks its border with surrounding Italy. The significant buildings are located in the eastern half of the “city.”

Manicured gardens and small buildings dominate the western half of the Vatican. Various pathways connect these gardens, while numerous fountains are scattered throughout the grounds.

There are no designated hiking trails within Vatican City. Those visiting Rome can also visit the Vatican and walk around the grounds, while entry to some buildings costs a small fee. In Rome, just west of the Vatican, lies the Monte Mario Nature Reserve, with numerous hiking trails. To the southwest lies the Riserva Naturale Valle dei Casali.

Geology

The geological history of Vatican City is deeply intertwined with the geology of surrounding Rome. A principal geological feature of the region, and much of Italy’s peninsula, is the Apennines, which span nearly 1,000 km (621 miles).

This range was formed by sedimentary rock deposited by ancient sea beds. Once buried, these deposits were put under immense heat and pressure due to tectonic and volcanic activity.

Around 20 million years ago, this immense pressure forced the range upwards to its current height. Despite their proximity to the Alps, the Apennines are geologically distinct. The Po Valley in northern Italy separates these two major ranges, while the valley subsides at a rate of 2-3 mm (0.1 inches) per year.

The Tiber River runs through Rome and has exposed sandstone and mudstone, contributing to the geological knowledge of the region. Past volcanic eruptions created the plateaus surrounding the city.

Ecology

Due to the urban nature of the Vatican, the country does not feature any distinctive fauna. Manicured gardens comprise nearly half of the city, with no sections of unmaintained landscaping. Plants traditionally growing in the surrounding region include various grass species, caper, thistle, knapweed, and cypresses.

Species introduced during the Roman Empire include lentils, pine nuts, grapes, apples, dates, olives, plums, and other edible plants.

Human History

Vatican City’s history dates back thousands of years. The name “Vatican” was used for another region of Rome during the Roman Republic. Agrippina the Elder first cleared the region of present-day Vatican City to build gardens during the first century AD.

The Romans eventually constructed the Circus Gaii et Neronis or Circus of Nero. Circuses were a venue for horse and chariot racing and one of the Roman culture's main entertainment centers. Although it was put into disuse after a couple of hundred years, the Circus survived mostly intact until 1450, when it was demolished to make way for St. Peter’s Basilica. The Vatican Obelisk is the final standing piece of the Circus of Nero and is in St. Peter’s Square.

Throughout the middle ages, Popes maintained a secular role as governors of the surrounding region of Rome. In addition to acting as the supreme leader of Christianity, the Pope governed the Papal States. These territories once covered a large portion of the Italian peninsula, and it was not until the mid-nineteenth century that the Kingdom of Italy seized control of this land.

Popes lived in the Lateran Palace on the other side of Rome for centuries, followed by the Quirinal Palace in 1583. Following the unification of Italy, the church began inhabiting the Vatican, while their previous residence became the residence of the King of Italy.

Rome was annexed by the Kingdom of Italy in 1870, and the Holy See, also known as the jurisdiction of the Pope, was left up for questioning until 1929. The Lateran Treaty of 1929, between the Holy See and the Kingdom of Italy, officially established Vatican City as an independent state. During World War II, Vatican City remained a neutral territory and was spared from bombing.
