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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
