The Basilica di Santa Maria Maggiore is a Papal major basilica and the largest Catholic Marian church in Rome. It is one of the only four churches that hold the title of 'major basilica' (all in Rome).
It is agreed that the present church was built under Pope Sixtus III (432-440). The dedicatory inscription on the triumphal arch, Sixtus Episcopus plebi Dei, ('Sixtus the bishop to the people of God') is an indication of that Pope's role in the construction. The church retains the core of its original structure, despite several additional construction projects and damage by the earthquake of 1348.
Santa Maria Maggiore, one of the first churches built in honour of the Virgin Mary, was erected in the immediate aftermath of the Council of Ephesus of 431, which proclaimed Mary Mother of God. Pope Sixtus III built it to commemorate this decision. The magnificent mosaics of the nave and triumphal arch depict scenes of her life and that of Christ, but also scenes from the Old Testament.
When the popes returned to Rome after the period of the Avignon papacy, the buildings of the basilica became a temporary Palace of the Popes due to the deteriorated state of the Lateran Palace. The papal residence was later moved to the Palace of the Vatican in what is now Vatican City.
The basilica was restored, redecorated and extended by various popes, including Eugene III (1145-1153), Nicholas IV (1288-92), Clement X (1670-76), and Benedict XIV (1740-58), who in the 1740s commissioned Ferdinando Fuga to build the present façade and to modify the interior. The interior of the Santa Maria Maggiore underwent a broad renovation encompassing all of its altars between the years 1575 and 1630.
The 5th century mosaics found in Santa Maria Maggiore are not just incredibly beautiful works of Late Antique art; they are also one of the oldest representations of the Virgin Mary in Christian Late Antiquity. The mosaics of the triumphal arch and the nave were the definition of impressionistic art during the time period and gave a model for the future representations of the Virgin Mary.
Under the high altar is the Crypt of the Nativity, with a crystal reliquary designed by Giuseppe Valadier said to contain wood from the Holy Crib of the nativity of Jesus Christ. Here is the burial place of Saint Jerome, the 4th-century Doctor of the Church who translated the Bible into the Latin language.
Beneath this altar is the Oratory or Chapel of the Nativity, on whose altar, at that time situated in the Crypt of the Nativity below the main altar of the church itself, Saint Ignatius of Loyola celebrated his first Mass as a priest on 25 December 1538.
Just outside the Sistine Chapel is the tomb of Gianlorenzo Bernini and his family.
The Mannerist interior decoration of the Sistine Chapel was completed (1587-1589) by a large team of artists, directed by Cesare Nebbia and Giovanni Guerra.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
