The Basilica of Santa Maria Maggiore stands on the Esquiline Hill as the largest Catholic Marian church in Rome and one of the city's four ancient major basilicas. Its main structure was commissioned by Pope Sixtus III and built between 432 and 440 AD — a direct response to the Council of Ephesus (431 AD), which formally proclaimed Mary as the Mother of God. Measuring 100 meters in length and 30 meters in width, the basilica has never been destroyed or entirely rebuilt, making it a rare, largely intact witness to early Christian ecclesiastical architecture. In 1980, it was inscribed as a UNESCO World Heritage Site as part of the properties of the Holy See.
The interior is defined by its extraordinary 5th-century nave mosaics — 36 panels depicting Old Testament scenes — and the triumphal arch mosaics commissioned by Sixtus III himself, which rank among the finest surviving examples of early Christian art in the world. The coffered ceiling, gilded with the first gold brought from the Americas and donated by the Spanish Crown to Pope Alexander VI in the late 15th century, stretches above a 13th-century Cosmatesque floor of inlaid geometric marble. The present baroque façade was designed by architect Ferdinando Fuga and completed in 1743, framing a portico that conceals medieval mosaic fragments by Filippo Rusuti dating to around 1300. Beneath the high altar, a crystal reliquary contains what tradition identifies as planks from the manger of Bethlehem — relics venerated here since at least the 7th century.
The basilica holds deep and living significance in Catholic devotion. Each year the Pope visits to pray before the Salus Populi Romani, a Byzantine icon of the Virgin Mary housed in the Borghese Chapel, a tradition maintained by every modern pontiff including Pope Francis, who visited after every foreign journey. That personal devotion shaped his final wish: on April 26, 2025, Pope Francis — who died on April 21, 2025, at the age of 88 — was laid to rest here, becoming the first pope in over a century to be buried outside the Vatican. Santa Maria Maggiore was also one of the Seven Pilgrim Churches of Rome along the 20-kilometer itinerary established by Philip Neri on February 25, 1552, a route still walked by pilgrims today.
Visitors should plan at least 90 minutes to absorb the full sweep of the basilica. The Loggia delle Benedizioni on the upper level — accessible by guided tour — offers close views of the medieval mosaics. Arrive early morning on weekdays to avoid tour groups and to see the mosaics lit by natural light filtering through the clerestory windows. Entry to the basilica is free, though access to the archaeological museum and the Loggia requires a ticket. The basilica is a short walk from Termini Station, making it a natural first or last stop on any Roman itinerary.
