The building in which the museum is sited was built in 1309 in the Gothic style and prior to the French Revolution housed Toulouse's Augustinian convent. The convent was secularized in 1793 and first opened to the public as a museum on 27 August 1795 by decree of the French Convention, very shortly after the opening of the Louvre, making it one of the oldest museums in France after the Louvre and the Musée des Beaux Arts in Besançon. It at first housed the Muséum Provisoire du Midi de la République and the école des Beaux-Arts. The Musée des Augustins de Toulouse was one of fifteen museums founded in provincial centres, by a decree of 13 Fructidor year IX, which was promulgated by the minister of the interior, Jean-Antoine Chaptal. At the start of the 19th century several medieval buildings were demolished and in their place Viollet-le-Duc and his pupil Darcy put up new exhibition galleries, accessed by a Gothic Revival monumental stair offering an interplay of richly complicated vaulting systems. The works continued from 1873 to 1901, when the museum reopened. In effect, Toulouse commissioned Urbain Vitry to ensure remove all the convent's religious characteristics. The archaeologist Alexandre Du Mège occupied the cloister and rebuilt it to be able to house the medieval collections gathered from Toulouse's destroyed religious buildings such as the basilique Saint-Sernin. Today the cloister houses a reconstructed medieval garden. The building was classed as a Monument historique in 1840.
Collections
The progressive concern of the museum's founder Jean-Antoine Chaptal, an early example of cultural devolution, was intended to ensure that "each collection presents an interesting series of paintings representing all the masters, all the genres and all the schools". In a series of shipments culminating in 1811, Toulouse was enriched with works by Guercino, Pietro Perugino, Rubens and Philippe de Champaigne. The collections total over 4,000 works and their core derives from confiscation of Church property at the time of the French Revolution as well as seizures of the private collections of emigrés, in Toulouse notably the paintings of the cardinal de Bernis and Louis-Auguste le Tonnelier, baron de Breteuil. The museum's church even houses an organ built in 1981 by Jürgen Ahrend when Denis Milhau was director of the musée between 1963 and 1994.
The museum's sculpture collection is in large part due to the rescue activities of antiquaries and museum curators such as Alexandre du Mège who managed to extricate sculpture from the frequent destruction of religious buildings that marked the 19th century. It is particularly strong in 12th-century Romanesque sculpture from the city's three main religious buildings - the priory of Notre-Dame de la Daurade, the basilica of Saint-Sernin and the cathedral of Saint-Étienne. Jorge Pardo realizes the new presentation of Romanesque sculpture. It also includes many 14th and 15th century locally-produced sculptures and eight 16th century terracotta figures from the chapelle de Rieux, built around 1340 in the couvent des Cordeliers, as well as gargoyles from the same convent. It also houses 19th century sculpture, with plaster works by Alexandre Falguière and his pupil Antonin Mercié, as well as works by Rodin and a bronze by Camille Claudel.
