Bastide du Jas de Bouffan, Historical mansion in Aix-en-Provence, France.

Bastide du Jas de Bouffan is a two-story manor house at 17 route de Galice, west of Aix-en-Provence. Its light ochre masonry facade is symmetrical, with a central dark wooden double door, a balcony with black wrought-iron railing above it, and pale-shuttered windows on both floors. A pale stone urn stands before the entrance, and the low-pitched roof is covered in terracotta curved tiles.

Georges Vallon designed the bastide for Gaspard Truphème, adviser to the Court of Audits, around 1730 (some sources say circa 1750). It passed through Truphème's descendants until banker Louis-Auguste Cézanne bought it in 1859. Paul Cézanne painted twelve large compositions in the oval salon between 1860 and 1870; these were detached and dispersed around 1912. The city of Aix acquired the house in the 2000s and reopened it as a museum in 2006.

Paul Cézanne painted twelve large mural compositions in the oval grand salon between 1860 and 1870; they were detached and dispersed around 1912. The garden's chestnut avenue and views of Sainte-Victoire appear in many of his works. The bastide reopened as a Cézanne museum in June 2025 after restoration led by Pierre-Antoine Gatier.

The bastide reopened to the public in June 2025 after renovation coordinated by chief heritage architect Pierre-Antoine Gatier, completed in 2020. Visits are by appointment only, so book ahead. Work on restoring the park to its appearance in Cézanne's paintings, and on building ticket facilities, was still ongoing.

The attic served as Paul Cézanne's private studio in 1880, where he captured mountain landscapes in oils and watercolors. These rooms still bear traces of his artistic exploration of natural forms.
