The term "Papal Basilica" refers to a church that has been granted special privileges by the Pope. These basilicas are significant in the Roman Catholic Church and often serve as important pilgrimage sites. There are four major Papal Basilicas, with the most famous being St. Peter's Basilica in Vatican City, which is a masterpiece of Renaissance architecture. Papal Basilicas are distinguished by their grandeur and historical importance. They typically feature elaborate artwork, stunning altars, and significant relics. In addition to St. Peter's, the other major basilicas include St. John Lateran, St. Mary Major, and St. Paul Outside the Walls. Each plays a vital role in the spiritual life of the Catholic community.
