Property of the La Bourdonnaye family, earls of Blossac, for nearly two centuries, it was leased by the city as the residence of the commander in chief of the province of Brittany, with a pomp reminiscent of the court of France.

The building was designated as a historic monument in 1947,[1] and underwent a complete exterior restoration spread over three decades, while the apartments give way to offices.

The hôtel de Blossac is located in the northwest in the secteur sauvegardé (protected area) of the historic city center.

As the hotel is a public building, it is possible, during office hours, visiting the external (courtyard and garden) and the staircase, including access to the documentation library.

Apart from the wooden stables, Hôtel de Brie by its stone construction, and thanks to the will of his owner not to build in wood, stop the burning of Rennes in 1720, protecting the western part of the city.

Hôtel de Brie probably communicated with the adjoining house, so called the Psalette, and also on the Rue Saint-Sauveur through the petit Fontenay.

The hôtel de Blossac will therefore occupy the entire width of the plot which is vested in maximizing the potential of this surface: the main body separated into two distinct parts (courtyard garden to the south and north side), rooms distributed in length.

This separation may have been conceived from the start of construction to put a home worthy of his office available to the intendant of the province, housed in the Hôtel de Brie.

Two boilers washing dishes, dishwashers ancestors, are installed in the backyard, and two drying cabinets are present in the service.

The garden, planted “à la française”, includes a central piece of turf with four statues around the corner, a round hollow in the bottom bay and fruit trees along the wall of the rue Saint-Sauveur.

Stables overlooking rue de Montfort are built the same year, to the great displeasure of neighbors whose plots are cropped.

They are half-timbered, established pursuant to the lease between the city and family La Bourdonnaye, to be dismantled at will, but vaulted brick inside.

Provided for twenty horses, they are insufficient and will be completed almost immediately through the leasing of other stables, rue du Pré-Raoult, outside the city walls.

Work continues, with hangars mounted in the service yard in 1732, a steakhouse near the stables in 1739 and in 1745, new joint opposite the hotel, overlooking the courtyard, still half-timbered.

Finally, a spacious garden for receptions, Estates of Brittany, concerts and dances, was built around 1760, known as the “nobles dining room”.

Gabriel projects concerning City Hall of Rennes, in 1732, going towards the construction of a large ensemble, including a separate building south of the site for the governor of the province of Britain.

There is a gatehouse, kitchen staff and service but also a Swiss, a baker and a butler, features a house of very high quality.

A chapel was then present at the first floor, while rooms are moved to return the north west, to enjoy the morning light.
