The church Santa Maria Maggiore (late 15th century) stands on the site of the former Lombard church of San Martino (founded in the second half of the 8th century). It has a rectangular shape with a polygonal apse and is oriented east-west. It has a single nave, divided by three arches. It is decorated with early 15th-century frescoes. The frescoes at the bottom of the north wall even belong to an earlier period. The contemporary wooden statue of the Madonna Enthroned is also of special interest.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
