As the town hall, it was also used for public events: on 2 September 1844, the pianist, Franz Liszt, performed a recital there, at a time when Lisztomania was at its height.

[3] In 1851, Jean Auguste Dominique Ingres, at 71 years of age, gave part of his collection, including copies, work of pupils, and Greek vases, as a gift to the city of his birth.

The death of Ingres in January 1867 led to a considerable enrichment of the collection with additional works, in particular several thousands of drawings.

A renovation carried out between 1951 and 1958 made Musée Ingres a modern institution according to the designs of the time, equipped with additional inventories.

Expanded, modernized and digitized, the museum now covers 2,700 m2 with new spaces, improved accessibility, a new museography, a conservation cabinet housing Ingres's drawings, an entire floor devoted to the work of Antoine Bourdelle, rooms for temporary exhibitions.
