Église du Saint-Esprit, Roman Catholic church in central Aix-en-Provence, France

The Église du Saint-Esprit stands at 40 rue Espariat, built in light tan stone blocks from 1706 to 1728 to designs by Laurent Vallon and his son Georges. Its facade is divided by flat vertical pilasters with carved capitals and topped by a triangular gable; a tall arched window sits above the main arched entrance, and a small arched plaque above the door reads "St Esprit".

Construction began in 1706 under architect Laurent Vallon and was completed in 1726, replacing an earlier hospital operated by the Order of the Holy Spirit. The church thus replaced an older institution during a period of urban renewal in the city.

The church holds a notable collection of artworks, including an Assumption of the Virgin triptych from the early 16th century and several paintings that came from a demolished noble residence. These treasures shape the interior and reflect its role as a keeper of local religious works.

The church is open daily and serves the community and students with regular worship services. Visitors should remember this is an active place of worship, so quiet and respectful conduct is expected when entering.

In 1750 the preacher Jacques Bridaine led a mission for the parish, and a large commemorative cross was set up outside the city; it now stands inside the church. The building also keeps a retable dated 1505, older than the 18th-century church itself.
