The name “Vatican” was used during the Roman Republic to refer to a marshy area located on the west bank of Tiber. Several villas were constructed there during the Roman Empire. Between 14 and 18 BC, Agripinna the Elder drained the area and planted a garden. Even before the arrival of Christians in the area, the Vatican was already considered sacred and not available for habitation. In 326, a Constantinian basilica was built in there, over what was believed to the tomb of Saint Peter. The activities at the Basilica led to an increased population at the Vatican, hence the construction of a palace in the 5th century. Popes soon became the governors of the regions near Rome, ruling the Papal State. The pope’s reign in the region came to an end in the mid-19th century following the unification of Italy. Pope’s influence was limited to the Vatican compound until 1929 following the signing of the Lateran Treaty. The treaty led to the founding of the state of Vatican City.
The region of Vatican City forms part of the Mons Vaticanus and the former Vatican Fields. The territory of Vatican City is where several historical and cultural sites are located; Saint Peter’s Basilica, Apostolic Palace, and the Sistine Chapel alongside other significant building. During the preparation of the Lateran Treaty, the boundary of the proposed state was influenced by the fact that the much of it was enclosed by the wall and certain buildings. The territory included the Saint Peter’s Square but normally patrolled by the Italian police Other properties located in the Italian territory such as the Papal Palace and the major basilicas have extraterritorial status, housing important offices, and institutions necessary for the mission of the Holy See. Vatican City experiences a Mediterranean climate which is characterized by a rainy winter and dry summer.
