medieval enclosure, known as "l'Huitrière"

En un regard

Le château en bref

The medieval enclosure known as "l'Huitrière" is an earthwork fortification on the bank of the Rance, in the Vigneux cove at Saint-Suliac. The site lies in an area that the sea covers at high tide. Its hexagonal plan, roughly 120 metres by 140, and its stone-faced embankments make it one of the few structures of this type preserved on the estuary. The Mérimée listing dates it only to the Middle Ages, for want of excavation. At the end of the nineteenth century, an oyster farmer holding the concession discovered iron objects, bones and timbers there during development works. One hypothesis, which remains to be confirmed, sees it as a Norman earthwork comparable to the Vieux M'na camp at Trans, and links it to the place of Gardoyne (or Gardayne) cited in the Roman d'Aquin, a twelfth-century text. Listed as a monument historique by order of 13 August 1986, the enclosure belongs to the public maritime domain and is owned by the State.
