The Basilica di Santa Maria Maggiore (English: Basilica of Saint Mary Major), or church of Santa Maria Maggiore, is the largest Catholic Marian church in Rome. Other churches in Rome dedicated to Mary include Santa Maria in Trastevere, Santa Maria in Aracoeli, and Santa Maria sopra Minerva, but the greater size of the Basilica of Saint Mary Major justifies the adjective by which it is distinguished from the other 25.
According to the 1929 Lateran Treaty, the basilica located in Italian territory is owned by the Holy See and enjoys extraterritorial status similar to that of foreign embassies. The building is patrolled internally by police agents of Vatican City State, not by Italian police. It is located on Piazza del Esquilino, number 34, some five blocks southwest of the Stazione Termini.
The church is sometimes referred to as Our Lady of the Snows, a name given to it in the Roman Missal from 1568 to 1969 in connection with the liturgical feast of the anniversary of its dedication on 5 August, a feast that was then denominated Dedicatio Sanctae Mariae ad Nives (Dedication of Saint Mary of the Snows). This name for the basilica had become popular in the 14th century in connection with a legend that the 1911 Catholic Encyclopedia reports thus: “During the pontificate of Liberius, the Roman patrician John and his wife, who were without heirs, made a vow to donate their possessions to the Virgin Mary. They prayed that she might make known to them how they were to dispose of their property in her honour. On 5 August, at the height of the Roman summer, snow fell during the night on the summit of the Esquiline Hill. In obedience to a vision of the Virgin Mary which they had the same night, the couple built a basilica in honour of Mary on the very spot which was covered with snow. From the fact that no mention whatever is made of this alleged miracle until a few hundred years later, not even by Sixtus III in his eight-line dedicatory inscription … it would seem that the legend has no historical basis.”
The original architecture of Santa Maria Maggiore was classical and traditionally Roman perhaps to convey the idea that Santa Maria Maggiore represented old imperial Rome as well as its Christian future. As one scholar puts it, “Santa Maria Maggiore so closely resembles a second-century imperial basilica that it has sometimes been thought to have been adapted from a basilica for use as a Christian church. Its plan was based on Hellenistic principles stated by Vitruvius at the time of Augustus.” Even though Santa Maria Maggiore is immense in its area, it was built to plan. The design of the basilica was a typical one during this time in Rome: “a tall and wide nave; an aisle on either side; and a semicircular apse at the end of the nave.” The key aspect that made Santa Maria Maggiore such a significant cornerstone in church building during the early 5th century were the beautiful mosaics found on the triumphal arch and nave.
