Musée national Jean-Jacques Henner, National art museum in 17th arrondissement of Paris, France.

The Musée national Jean-Jacques Henner occupies an 1878 hôtel particulier by architect Nicolas-Félix Escalier at 43 avenue de Villiers, in the Plaine-de-Monceaux quarter. Its grey rusticated ground floor has a dark wooden door flanked by two tall iron grilles, with the number 43 on a blue plaque and a stone band inscribed MUSEUM NATIONAL J.J. HENNER. Above, a balustrade with two flags and a dark bust fronts three tall windows, and carved medallions run beneath the upper stonework. Two storeys were added in 1935 by architect André Arfvidson.

Architect Nicolas-Félix Escalier built the hôtel particulier at 43 avenue de Villiers between 1876 and 1878 for the painter Roger Jourdain; Guillaume Dubufe bought it in 1878. Marie Henner, widow of the artist's nephew Jules Henner, purchased it from Dubufe's heirs in 1921 and gave it to the State on 19 June 1923. The museum opened to the public in 1924, with Henner's pupil Many Benner as first curator, and became a national museum in 1943.

The collection shows paintings from portraits to mythological scenes, reflecting how French artists shifted from observing nature closely to exploring spiritual and symbolic themes. Walking through the rooms, you see how artists gradually embraced imagination and emotion over strict realism.

The museum occupies the 1878 hôtel particulier at 43, Avenue de Villiers, in the Plaine-de-Monceaux quarter of the 17th arrondissement. The visit runs through three floors: the former dining room serves as an introduction, the columned salon and winter garden are on the ground floor, and the red rooms and grey studio are above. The winter garden also hosts temporary exhibitions, concerts and performances.

In 1888 the painter Guillaume Dubufe bought mashrabiya screens from the Goupil collection and installed them in his first-floor studio; they still stand there, and the small room behind them now hosts graphic-art exhibitions. The building was raised by two floors in 1935 under architect André Arfvidson.
