Château de Rimaison, Renaissance castle ruins in Pluméliau-Bieuzy, France.

Château de Rimaison is a ruined castle in Pluméliau-Bieuzy, Morbihan. Only the vestibule remains in place: two light-stone arches joined by a central pier, each keystone carved with a face, the left arch open with steps and the right holding a small staircase. The rest was dismantled, leaving low broken fragments at the base.

Built in the 16th century, perhaps in 1579, on the site of an earlier manor, the castle belonged to the Rimaison family from the 15th to the 18th century. In 1749 the lands passed to the Guergolay family. Sold as national property in 1794, it was already in ruins and served as a stone quarry for local residents; stones bought by Patern Le Mouel in 1817 were used to build the Kerdanet farm in Le Sourn.

The name Rimaison comes from the family who held these lands from the 15th to the 18th century, before they passed to the Guergolay family in 1749. The site also held a chapel dedicated to Saint Remy, whose remains were found among the other building traces. The Breton name Porzh Rivezon is still used for the place.

The ruins are now part of a nine-hole golf course, so you can explore the site while golfers play nearby. Keep in mind that you will need to be careful and aware of golfers to safely move around the historical structures.

The fireplace classified as a monument historique in 1953 was sold and moved in the early 1950s to the fortin de Port Maria at Locmaria on Belle-Île-en-Mer. The castle stones themselves were bought in 1957 by Xavier Ollivier and carted off to rebuild the château de Kergluyar at Pluvigner. Only the vestibule arches still stand on the original site.
