Created in 1810, Avignon's cabinet of natural history blossomed thanks to the Avignonese naturaliste Esprit Requien (1789-1851). This botanist, malacologist and paleontologist put together an important collection which has continued to expand (over 1,2 million specimens at this day). He is also behind an important scientific library (18,000 volumes of which 3,300 from the 16th to the 19th century, 20,000 off-prints, 23 active reviews). The permanent exhibition halls propose an introductory visit covering the history of the earth and its animal populations. In addition, the museum organizes several temporary exhibitions each year. It hosts several naturalists' organizations who convene for conferences opened to the public. It is associated with international scientific programs and also takes part in national events (Nuit des musées, Fête de la Science, Journées européennes du Patrimoine, etc.)
