Since September 2003 the Joseph-Abeilhé museum has been one of the listed "Museums of France". This museum in the town hall has a beautiful collection of birds (around 300), mammals, fossils and minerals. The showcases are like cabinets of curiosity displaying amazing items, stuffed animals, sea shells and other shells. The section devoted to palaeontology is particularly well endowed with fossils of plants and invertebrates.
Charles de Batz-Castelmore, who later took the name of his mother "de Montesquiou d'Artagnan" to increase his chances in Court, really existed. It was under this later name that he was immortalised in the novel by Alexandre Dumas. Born near Lupiac, he died in the Siege of Maastricht.
In 1998, the town of Lupiac opened a museum which traces the life of this character as it would have been lived back then.
In 1832 Joseph Delort, who was born in Gers, was head of the fine arts section in the Interior Ministry. He opened a museum in his town. Since then, the collection has increased to the extent that it has become one of the main collections in Gers along with the one in Auch.
It includes a significant number of paintings from the Flemish, Italian and French schools from the 15th to the 19th centuries and pieces of faience made in the Southwest.
