Building the 18th arrondissement of Paris, the mansion Lejeune was built in 1927 by Adolphe Thiers for the sculptor Louis-Aimé Lejeune. Elegant building of Art Deco style, it takes place in the district of Montmartre.
A bas-relief on the facade represents in particular the artist at work, and the workshop of Louis-Aimé Lejeune has conserved over the years its Art nouveau decoration.
