Tourism in Vatican City
The Vatican was built during the year 326 A.D. As the population and housing grew, the first palace was built during the 5th century under the reign of Pope Symmachus (498–514). Under the Holy Roman Empire, the Papal States grew to include a large portion of central Italy. But since the unification of Italy in the mid-19th century, Vatican City is the only papal state that has survived. As of 1929, because of the Lateran Treaty, the Vatican is recognized as its own independent state, the smallest in the world in population and land size, with a population of just over 800 people in July 2011. The Pope is not only the head of the Catholic religion but also head of state for Vatican City. Since the Vatican is located in Italy, the main language of the Vatican state (or Vatican City) is Italian.
Vatican City
Vatican City's climate is the same as Rome's: a temperate, Mediterranean climate "Csa" with mild, rainy winters from October to mid-May and hot, dry summers from May to September. Some minor local features, principally mists and dews, are caused by the anomalous bulk of St Peter's Basilica, the elevation, the fountains and the size of the large paved square.
In July 2007, the Vatican accepted a proposal by two firms based respectively in San Francisco and Budapest, whereby it would become the first carbon neutral state by offsetting its carbon dioxide emissions with the creation of a Vatican Climate Forest in Hungary, as a purely symbolic gesture to encourage Catholics to do more to safeguard the planet. Nothing came of the project.
