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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
