Origin and history
The Kerascoet mansion, located in Pluguffan in Finistère, was originally the seat of a modest seigneury in the 15th century. Although its origins date back to this period, the current building is the result of a complete reconstruction carried out in the 18th century. This reshaping now gives it a homogeneous appearance, characteristic of the small Breton manors organized around a square courtyard. Notable architectural elements include entrance pillars, a rabine (water channel) and a double enclosure surrounding the garden, reflecting the evolution of local seigneurial practices.
The north facade of the mansion underwent major alterations in the 20th century, partially compromising its historical authenticity. In 1945, a garage was added as an extension of the sill, and in 1970 two rooms were built on both sides of the stairway tower. Despite these modifications, the fronts and roofs on the courtyard, as well as the garden with its double enclosure and the rabine, were protected by an inscription under the Historic Monuments on 13 March 1991. This classification highlights the heritage value of the site, representative of Breton manorial architecture of the 17th and 18th centuries.
The mansion illustrates the transition from a modest medieval seigneury to a more cossuous residence, adapted to the standards of the seventeenth and eighteenth centuries. His plan in square courtyard, typical of the region, met both residual defensive needs and a desire for social prestige. The presence of a rabine and a double enclosure also demonstrates the importance attached to landscape aesthetics and to the symbolism of power, even for middle-sized seigneuries. These developments reflect the architectural influences of the period, combining medieval heritage and classical innovations.
