The current structure of Chiesa Parrocchiale di Saint-Vincent, with a large circular apse, dates back to the 15th century, when important changes were made to a probable, pre-existing Romanesque building. For some time it conserved certain parish church prerogatives (festive functions and cemetery), even though it was never a parish church.The apse vault has a beautiful series of ribbed stone. Recent restoration removed the modern structures and decor, in an attempt to restore the church to its original appearance. In the past, on Easter Monday, the so-called “vineyard procession” took place, which in almost six hours passed through all the villages and chapels on the Saint-Vincent hillside.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.
