San Gaudenzio is a Baroque architecture church in the town of Ivrea. Tradition holds that the church is located on a site where St Gaudentius in the year 348 had lain down on a rock overnight, and his body miraculously left an imprint on the rock. The church was constructed between 1716 and 1724 at the site of a former castle. The bell tower was built in 1742. The architect remains unknown, although the rococo design of the facade with a convex front and an oval tympanum appears influenced by Bernardo Antonio Vittone. Some attribute the design to Luigi Andrea Guibert, active in Ivrea between 1714 and 1719. The interior contains frescoes (1738–1739) by Luca Rossetti.
The church has a number of paintings depicting the scenes in the Life of St Gaudentius, including a Glory of the Saint in the apse, behind the main altar. One is a procession leaving the chiesa di San Gaudenzio with the city in the background.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.
