4 659€/m²

The average price of apartments in Sarzeau stands at 4 659 €/m², based on DVF transactions actually registered with notaries. The largest municipality of the Rhuys peninsula, south of the Gulf of Morbihan and some twenty kilometres from Vannes, Sarzeau brings together a fortified village, a long coastline and a farming hinterland. Its market is strongly marked by the second home, which accounts for close to six homes in ten, and by the seaside appeal of the gulf. Prices sit clearly above the departmental average, driven by the scarcity of coastal land and by a clientele of holidaymakers and retired people. Closeness to the sea, aspect, the view and distance to the beaches and the village weigh heavily on value from one property to another.

Market trends and analysis for Sarzeau

The Sarzeau market is that of a prized seaside municipality of the Gulf of Morbihan, where the second home holds a decisive place. The Rhuys peninsula, with its coastline, its beaches and its heritage, attracts demand from holidaymakers and retired people that reaches far beyond the local area. This pressure, combined with the scarcity of coastal land, keeps prices clearly above the Morbihan average and holds the value of well-located properties firm.

Several factors sustain the appeal of the municipality: the quality of the natural setting, the closeness of Vannes, the standing of Suscinio castle and the choice of beaches and harbours. Conversely, strong seasonality and the high share of second homes make the market sensitive to the tourist climate and to the ability of households to invest in a holiday property. The value of a property here depends closely on its closeness to the sea, its aspect and its view.

The history of Sarzeau

Sarzeau occupies the centre of the Rhuys peninsula, that long tongue of land which closes the Gulf of Morbihan to the south. The territory, settled for a very long time, was organised around a farming village and hamlets turned towards both land and sea. Between the 13th and the 15th century, the dukes of Brittany had Suscinio castle built here, a vast fortress surrounded by marshes and woodland that became one of their favourite residences, a few kilometres from the village.

After Brittany was attached to France, Suscinio lost its role as a ducal residence and gradually fell into decay. The castle was listed as a historic monument in 1840, at the instigation of Prosper Mérimée, then restored through the 20th century by the department of Morbihan, which owns it today. Sarzeau is also the birthplace of the writer Alain-René Lesage, born in 1668, author of the novel Gil Blas de Santillane.

Long rural and maritime, the municipality lived off farming and oyster farming, the oyster beds spreading along the Pénerf river and in the gulf. From the 20th century, seaside tourism transformed the peninsula: beaches, marinas and second homes multiplied. Sarzeau became one of the most prized municipalities of the Morbihan coast, while keeping its village, its heritage and a large share of natural and farming land.

Who buys in Sarzeau

Sarzeau has a little more than 9 200 permanent inhabitants, but its population swells sharply in the summer season. The housing stock is marked by the weight of the second home, which accounts for close to six homes in ten, a feature of the seaside municipalities of the Gulf of Morbihan. Main residences are mainly houses, in the village and the many hamlets, while the coast concentrates villas and holiday properties. Buyers are in part holidaymakers and retired people looking for a base by the sea, which supports high prices and demand geared to the areas close to the beaches and the gulf.
