The largest church in Castres, in the Tarn, Saint-Benoît cathedral was elevated to its rank at the beginning of the 14th century before becoming a parish church at the beginning of the 19th century. Listed as an historic monument, it dates back to the 11th century, the time of its current Romanesque-style bell tower, and has undergone many transformations over the centuries, notably with a body built in the 17th century.
Mainly in the Baroque style, the building reveals a narrow nave of four bays bordered by several chapels and vestibules. Visitors can also admire in the choir gilded wood trophies surrounded by four 17th century marble statues from the Charterhouse of Saïx.
Separated from the body of the church, the bell tower was attached to the episcopal palace of Castres, revealing an architecture close to a bell tower-keep with its flattened buttresses.
