Avignon Cathedral is the seat of the Archbishop. The cathedral is a Romanesque building, built primarily in the second half of the 12th century. The bell tower collapsed in 1405 and was rebuilt in 1425. In 1670-1672 the apse was rebuilt and extended.
The building was abandoned and allowed to deteriorate during the Revolution, but it was reconsecrated in 1822 and restored by the archbishop Célestin Dupont in 1835-1842. The most prominent feature of the cathedral is a gilded statue of the Virgin Mary atop the bell tower which was erected in 1859.
The interior contains many works of art. The most famous of these is the mausoleum of Pope John XXII (died 1334), a 14th-century Gothic carving. It was moved in 1759, damaged during the Revolution, and restored to its original position in 1840. The cathedral was listed as a Monument historique in 1840.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
