Every August, white petals fall inside a Roman basilica to recall summer snow
Legend says snow fell on Rome's Esquiline Hill one August night in the fourth century, marking where the Virgin Mary wanted a church. The story surfaced only after the year 1000, yet Santa Maria Maggiore still honours it each 5 August by releasing white rose petals from its dome during Mass.
According to the tale, a childless patrician named John and his wife vowed their fortune to Mary around 352 and asked how to spend it. That night, at the height of summer, snow covered the hilltop, and a vision told them to build there. A later version adds that Pope Liberius dreamt of the snowfall too and traced the church's outline in it. Church reformers proposed dropping the legend from the liturgy as early as 1741, but nothing changed until 1969.
History tells a plainer story. The present church went up on the Cispian spur of the Esquiline under Pope Celestine I and was consecrated on 5 August 434 by his successor Sixtus III, whose name appears in the inscription over the triumphal arch. It followed closely on the Council of Ephesus in 431, which declared Mary the Mother of God, and its nave and arch mosaics are milestones in how she was depicted. The design deliberately resembles a second-century imperial basilica, and scholars link the lavish work to the papacy's efficiently managed estates, whose income was split between administration, clergy, buildings and charity.
Before the snow story spread, the church was known as Saint Mary of the Crib, after sycamore boards venerated as the manger of Jesus. It also holds the icon Salus Populi Romani, regarded as protector of Rome. When plague struck in 590, Gregory the Great sent seven processions through the city to converge here rather than at St Peter's. After the Avignon period, popes lived in its buildings while the Lateran Palace lay in disrepair.
Although it stands in Italian territory, the Lateran Treaty of 1929 gives it the immunity of a foreign embassy as property of the Holy See. It is one of only four major basilicas, excavations beneath it in 1966 revealed a Roman calendar, and Pope Francis was buried in its side nave in 2025.
