The Romanesque Santa Maria (St. Mary's) church, which is located at the foot of the medieval castle, was the seat of the parish until the end of the 18th century. The bell tower is a typical square shaped tower. During the digs carried out in the building, the remains of the ancient early-Christian church and the relative baptismal font were found. The semi-circular shaped crypt, near the choir, dates back to the 11th century. Inside the church you can still admire important frescos from the 13th to the 16th century, as well as furnishings.
You can access the church on foot, within the space of five minutes, from the road that unwinds from the bridge over the Dora Baltea.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.
