The Basilica di Santa Maria Maggiore is one of the four papal basilicas in Rome and the largest church in the city dedicated to the Virgin Mary. Founded in the 5th century under Pope Sixtus III, it is renowned for its well-preserved Early Christian mosaics and its status as the first Marian sanctuary in the Western world. The basilica holds a unique position in Roman ecclesiastical history, serving as a major pilgrimage site and a repository of significant religious relics.
The structure displays a complex architectural evolution, featuring a 5th-century nave, a 13th-century Romanesque campanile—the tallest in Rome—and extensive Renaissance and Baroque additions. Its interior is celebrated for the 5th-century mosaics depicting Old Testament scenes, the intricate Cosmatesque floor, and the ornate coffered ceiling, which is said to be gilded with gold brought from the Americas by Christopher Columbus.
