Maison rose, Pink residence in Séné, France

Maison rose is a large two-storey house with two symmetrical wings and a slate roof, standing at the tip of the Séné peninsula beside the narrows where the Vannes river and the Vincin meet the Gulf of Morbihan. Its sea-facing facade is painted pink, with nineteen openings in all, nine of them on the main facade, and white shutters. The property has a quay and a slipway and is surrounded by a large wooded park, less than 100 m from Arradon on the opposite bank.

Built in 1879 for Mathurin Juteau, an oyster farmer from Vannes, the house gained its quay in 1880 and its slipway in 1897. These works tied the property to the oyster trade of the Gulf of Morbihan. It remains in private hands today.

The pink facade acts as an official reference point for boats entering the port of Vannes, as noted in the maritime instructions for the area. This makes the building one of the few private homes whose exterior color has a direct role in local seafaring.

The property is privately owned and cannot be visited, but it is clearly visible from the water or from the waterside paths nearby. Approaching by boat gives the clearest view, as the house faces directly onto the channel.

The sea-facing facade cannot be altered by the owners, even though the building is not listed as a Historic Monument. Its pink colour is recorded by the SHOM in the nautical instructions for the Gulf of Morbihan, so the navigation mark is protected by its use rather than by heritage status.
