Built around 1760 by Chevalier Aaron Pierre Magon, the Montmarin stands out for its grace and fanciful design, contrasting with the more austere malouinières on the right bank of the Rance.
After Magon’s death, the estate was acquired by Benjamin Dubois, a shipowner and naval builder from Saint-Servan. He transformed the property into a thriving shipyard, capable of building up to ten ships at once. With special privileges from the Royal Navy, more than 300 vessels were constructed here, employing over 1,200 workers.
Between 1782 and 1813, the estate underwent major changes: the shipyard was converted into a tidal mill, then restored and enhanced by Louis Bazin de Jessey, who created French formal gardens and romantic landscapes.
In the 20th century, despite bombings and the devastating storms of 1996 and 1999, the de Ferrand family restored the estate and the pavilion at Menus Fillains, the last surviving remnant of the shipyard. Thanks to their work, visitors can now discover the rich historical heritage of Montmarin.
For three generations, the de Ferrand family has cared for and maintained the estate. Thanks to meticulous restoration work and the organization of cultural events and guided tours, Montmarin has become a vibrant place where maritime and botanical heritage can be explored with passion.
