A jewel of Aix's architectural heritage, the Hôtel d'Oraison is a grand private mansion whose origins date back to the late 16th century. Initially the property of Henri de Raffelis, it welcomed among its guests the Duke of Guise, Governor of Provence, reflecting from its very beginnings a prestige of the highest order.

It was in the 18th century that the building took on its current form: the Marquis d'Oraison, Mathieu Fulque, acquired and merged several houses between 1731 and 1736 to compose an architectural ensemble befitting his rank. The result is a majestic seven-bay façade adorned with vertical rustication, windows featuring acanthus ornamentation and mascarons, as well as two carriage gateways, one of which is crowned by an elegant balcony with a triangular pediment — all hallmarks of Aix's Baroque style in its full splendour.

Confiscated during the Revolution in 1792, the mansion passed through the centuries in the hands of notable figures and prominent members of the city's academic community, before being listed as a historic monument in 1987 and carefully restored in 2012.

The building is currently divided into individual apartments, arranged as follows:

- A 66.4 sqm apartment on the ground floor.
- A 93.9 sqm apartment with a 169 sqm garden, spanning the garden level, mezzanine and first floor.
- A 211 sqm office-style apartment on the first floor.
- A 58.1 sqm apartment on the second floor.
- A 104.7 sqm apartment on the second floor.
