Malouinière du Bosc, 18th century manor house in Saint-Malo, France.

Malouinière du Bosc is a large pale stone manor house at the entrance to the village of Quelmer, on the bank of the Rance in Saint-Malo. Its central block has a projecting entrance bay topped by a curved pediment, flanked by two lower wings under a steep dark slate roof with three tall chimneys and small dormer windows. The former manor became the outbuildings, and the house opens through a perron onto a green carpet perspective.

Built between 1715 and 1718 for shipowner Pierre le Fer de la Saudre and his wife, widow of a Magon de la Chipaudière, the manor belonged to Saint-Malo's Magon family of shipowners and privateers. Its neighbour across the Rance estuary, Montmarin, was built in 1760 by Aaron-Pierre Magon du Bosq and had the same owner at the time. The manor, its park and boundary walls were inscribed as monuments historiques on 19 October 1994.

The name malouinière comes from Saint-Malo: these were pleasure houses built by the city's shipowners and corsairs. The Bosc was built on the same model as La Chipaudière and La Balue, both also owned by the Magon family, which the source calls rare. In the park, white marble busts imported from Italy evoke the Seasons around the perron rotunda.

The estate sits near Saint-Malo along the Rance river and is accessible by walking through the grounds. The layout allows visitors to see the buildings and garden areas together during a single visit.

The Bosc was built on the same model as the Chipaudière and Balue malouinières, both also owned by the Magon family, which the source calls fairly rare. The old manor was converted into outbuildings, and the main house opens through a perron with a green carpet. White marble busts imported from Italy, evoking the Seasons, mark the perron rotunda.
