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 Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
