Vatican City may be small, but it's steeped in religious history.
It has a long history of being strongly linked with Christianity as the site of Saint Peter's tomb as well as being filled with famous churches, museums and beautiful gardens that millions visit every year. Vatican City was designated a UNESCO World Heritage Site in 1984. It became an independent state in February 1929, as defined by the Lateran Treaty.
Vatican City is deemed the smallest country in the world. The city-state in Italy is landlocked in Rome and operates with its own telephone system, post office, gardens, radio station and more, per Britannica. Most of the supplies that Vatican City uses to remain functional are imported.
