Prefecture hotel of Réunion, Government building in Saint-Denis, France.

The Prefectural Building is an administrative facility in Saint-Denis featuring classical architecture with tall windows and ornate railings along its facade. The structure sits near the Barachois district and maintains its original roof design and proportions.

The building serves as the seat of the prefecture of La Réunion and the residence of the prefect, at the Barachois in Saint-Denis. Its facades and roofs were classified as monuments historiques on 12 August 1970, and the rest of the building was inscribed on 9 February 2006. With the Chapelle Pointue in Saint-Paul, classified the same day, it is the oldest classified edifice on the island.

The building is the seat of the prefecture of La Réunion and the residence of the prefect, so its cultural role is administrative rather than touristic. Its facades and roofs were classified as monuments historiques on 12 August 1970, the same day as the Chapelle Pointue in Saint-Paul, making it one of the oldest classified edifices on the island. The rest of the building was inscribed on 9 February 2006.

The building stands at the Barachois in Saint-Denis, behind dense trees and palms that partly screen the facade from the street. Look for the white rendered front with its grey hipped roof and flagpole; the projecting central bay, wrought-iron balcony and round-arched doorway are best seen from the open ground facing it. It is a working prefecture, so visits concern the exterior.

The facades and roofs were classified as monuments historiques on 12 August 1970, and the rest of the building was inscribed on 9 February 2006. The same 1970 classification covered the Chapelle Pointue in Saint-Paul, making the two the oldest classified edifices in Réunion.
