Castres Cathedral (Cathédrale Saint-Benoît de Castres), now the Roman Catholic church of Saint Benoît, was formerly the seat of the bishop of Castres, but the diocese was not restored after the French Revolution and was added by the Concordat of 1801 to the Archdiocese of Albi.
The first cathedral was built in the 14th century after the creation of the diocese of Castres in 1317, along with a number of other dioceses created in the region after the suppression of the Albigensians. It was destroyed during the French Wars of Religion.
The present building which replaced it was constructed in the 16th and 17th centuries.
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.
