Saint-Dié Cathedral, formerly a collegiate church, is dedicated to Saint Deodatus of Nevers. Since 1777 it has been the seat of the Bishop of Saint-Dié.
The cathedral, like most of the town, is built largely of the local red sandstone. It has a Romanesque nave (12th century) and a Gothic choir; the portal of red stone dates from the 18th century. A fine cloister (13th century), containing a stone pulpit, communicates with the Petite-Église or Notre-Dame de Galilée, a well-preserved specimen of Romanesque architecture (12th century).
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.
