Papal basilicas are important churches in the Roman Catholic Church, designated by the Pope. They hold special significance and are often sites of major religious events. There are four major papal basilicas, including St. Peter's Basilica in Vatican City, which is renowned for its stunning architecture and art. These basilicas are distinguished from other churches by their unique privileges, such as the ability to grant indulgences. They often serve as pilgrimage sites, attracting visitors from around the world who come to admire their beauty and participate in religious ceremonies.
