The Musée du Petit Palais is a museum and art gallery. It opened in 1976 and has an exceptional collection of Renaissance paintings of the Avignon school as well as from Italy, which reunites many 'primitives' from the collection of Giampietro Campana. It is housed in a 14th-century building at the north side of the square overlooked by the Palais des Papes.
Named Petit Palais to distinguish it from the Palais des Papes, the original structure was built during the period of the Avignon Papacy by Cardinal Bérenger Fredoli the Elder in around 1318-20. The palace and a few neighbouring buildings were bought on de Frédol's death in 1323 by Cardinal Arnaud de Via, nephew of the reigning Pope John XXII. When de Via died in 1335 Pope Benedict XII bought the building for use as the episcopal palace. The subsequent building work created an interior close to that of the present configuration with four wings around a cloister and a service court.
The building suffered during its use from 1396 as a fortified citadel during the Western Schism, and was a wreck by the time the war ended in 1411. In the second half of the 15th century, Bishop Alain de Coëtivy and his successor, Giuliano della Rovere (the future Pope Julius II) carried out restoration work, giving the Palace more or less its present appearance by 1503. Della Rovere arrived in Avignon in 1474, having been made bishop of Avignon and papal legate of Avignon by his uncle Pope Sixtus IV. He added new south and west facades in Italian Renaissance style and, in 1487, a tower (which collapsed in 1767). The Palace became known as the Palace of the Archbishop when the city was promoted to an archbishopric soon after della Rovere took office.
During the French Revolution, the palace was nationalised and sold off, becoming a Catholic secondary school in 1826 and then in 1904, with the separation of the church and the state, a professional and technical school.
The collection includes 327 works by Italian and French primitive or early-renaissance painters such as Sandro Botticelli or Vittore Carpaccio. There is also 600 sculptures including the effigy head from the tomb of Antipope Clement VII.
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.
