Forcalquier Cathedral, now the Church of Notre-Dame-du-Bourguet, is a former Roman Catholic cathedral, and a national monument of France. Erected in the 12th century as a collegiate church, the cathedral of Forcalquier became a second seat of the Bishop of Sisteron in 1408, and for that reason is referred to as a co-cathedral. The diocese of Sisteron was abolished in 1801, after which the cathedral continued as a parish church.
The nave, the choir, the transept and the cloister date from the early 13th century, representing one of the first examples of Gothic style in southern France. The bell tower is from the 16th century. The church houses a panel of the Triumph of Christ by Pierre Mignard.
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.
