Vienne Cathedral, dedicated to Saint Maurice, was the epicopal see of the primate of the ancient Septem Provinciae and of the Archdiocese of Vienne until its abolition confirmed by the Concordat of 1801. It today serves as co-cathedral of the Diocese of Grenoble-Vienne. The present-day building was erected from 1130 onwards.
Mentioned as the burial place of the Burgundian king Boso of Provence in 887, no traces are left from the former church buildings at the site. Construction works at Vienne Cathedral are documented under the tenure of Archbishop Léger from 1030 to 1070.
The construction of the preserved church was begun in a Late Romanesque style about 1130. Built over a long period, Gothic modifications and extensions were carried out until its consecration by Pope Innocent IV on 20 April 1251. From 1311, Pope Clement V convened the Council of Vienne, where the clergy resolved upon the dissolution of the Knights Templar. The facade was added in the 16th century, with the capstone ceremony held in 1529.
The present-day building is a basilica, with three aisles and an apse, but no ambulatory or transepts. The most striking portion is the west front, which rises majestically from a terrace overhanging the Rhône. However, the sculptural decoration was badly damaged by plundering Huguenot forces under Baron François de Beaumont in 1562, during the French Wars of Religion.
In the wake of the French Revolution, the Vienne archdiocese was dissolved and the former cathedral became a plain parish church, while the surrounding premises temporarily served as barns or barracks and eventually were demolished.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
