Devenue bien national, elle abrita le sinistre Tribunal Révolutionnaire
puis, rachetée et restaurée par la famille Cornudet, elle échappa de
justesse à la pelleteuse grâce à un sursaut d’intérêt pour ce patrimoine,
suite à un  referendum communal favorable à sa démolition en 1973.

Le cliché des années 30 rappelle que lors des imposantes processions de
la Fête-Dieu qui sillonnaient les rues de la paroisse, les habitants du
quartier y installaient un éphémère décor floral.

Records in the Abbey of Redon confirm that the first construction of a chapel date from 1063, when an Act was signed by the Rector of Nivillac.  Originally Catholic, the chapel became, in 1561, the first Protestant place of worship in Brittany.  During the Revolution, the building became national property and housed the sinister Revolutionary Tribunal Court.  During the restoration in the 19th century, the Chapel was bought from the Nation by a local family, the Cornudet family.  Having fallen into disuse and partially ruined, the local council decided to demolish the chapel in 1973.  However, following a Communal Referendum, an Association was set up to restore the building to its former glory.  A photograph taken in the 1930s shows the Chapel decked in  flowers for the Fête Dieu.
