Musée Bonnat-Helleu, Art museum in Bayonne, France
The Musée Bonnat-Helleu is an art museum in Bayonne that houses over 6,500 works from various periods, including paintings by Spanish and British artists alongside an extensive collection of 3,500 drawings. The holdings span from medieval times to the modern era, representing both well-known and lesser-known artists across different European artistic traditions.
The building was designed by architect Charles Planckaert after a December 1889 fire destroyed Bayonne's town hall and much of its archives. Its first stone was laid in 1896 by mayor Léo Pouzac, and it opened in 1901 housing archives, a library, a painting museum and a natural history collection. It has been devoted entirely to the museum since 1976 and was renamed Musée Bonnat-Helleu in 2011.
The museum's name honours two Bayonne-linked painters: Léon Bonnat, born in the city in 1833, and Paul César Helleu, whose daughter Paulette Howard-Johnston gave and bequeathed over 300 of his works. The Helleu holdings, built from a 1989 gift and a 2010 legacy, are among the largest anywhere.
The museum reopened on 27 November 2025 after closing on 11 April 2011. The renovation doubled the surface from 2,000 to 5,000 m² by annexing the neighbouring Petit Bayonne primary school, so visitors now enter through the former school and its courtyard, with the historic central patio reworked. The final cost reached 35 million euros.
The collection of drawings and prints is one of France's largest outside Paris, spanning works from multiple centuries. These works on paper often show the artists' own notes and sketches, revealing how they approached their creative process.
