The history of the chapel of Briord is not that of a single building. A medieval "little chapel of the court", a "new chapel" in the park dedicated to Saint James, and finally the present building erected or enlarged by Michel-Adolphe Pelet de Lautrec and solemnly blessed on 15 June 1853, consecrated to Saint Germain and the Virgin. Abbé Jean Bouchard, unsworn chaplain of Joseph Charette, perished in the drowning of 16 November 1793. The Théotiste Covarel affair (1877) broke out in the countess's bedroom. Successive strata that make the heritage singularity of the estate.
The history of the chapel of Briord is not that of a single building but that of several successive constructions, whose traces overlap in the archives. A document of the revolutionary administration, dated 1793, mentions a "little chapel of the court" within the very medieval quadrilateral; its exact location in the buildings that disappeared in the 18th century remains unknown. Another chapel, called the "new chapel" and consecrated to Saint James, stood in the château's park. It benefited from an endowment based on several métairies of Sainte-Pazanne, charged "with a Mass on Sunday and Monday alternately each week, said at Briord when the lords are there, otherwise in the church of Port-Saint-Père at the altar of Saint John". The present building dates from the mid-19th century: restored under the Restoration then enlarged, it bears the architectural trace of a long history.
At the end of the 15th century, when Pierre Landais had his "house and manor" of Briord fortified — the digging of the moats, drawbridge, enclosure — there probably existed within the manorial quadrilateral a seigneurial chapel. The layout of the contemporary great Breton houses — Le Plessis-Josso, Le Bois-Orcan, L'Étier, Le Gué-de-l'Isle, all built by intimates of Duke Francis II — shows similar arrangements. But no medieval document of Briord describes it precisely: the homages rendered to the duke and then to the king are limited to enumerating the rents of the fief.
An inquiry of 1688 places a "room of the religious" on the upper floor of the manor; in 1747, the inventory mentions the "priest's room", occupied by the chaplain who also served as tutor to the Charette children. This stable ecclesiastical presence in the dwelling indicates a regular religious service, probably in the little chapel of the court. As for the park chapel dedicated to Saint James, it predates the 19th century — there survives, in the central part of the present building, a motif carved in tuffeau representing the coat of arms of the Charette family.
Near the chapel, a secondary building housed worship: an oratory raised under the episcopate of Bishop de Sanzay at the beginning of the 18th century, where "Mass was celebrated within the house". This oratory — according to the archives examined — occupied the location or site of the building known today as the chaplaincy, which faces the chapel from the other side of the main avenue. It was therefore at the beginning of the 18th century, and not under Joseph Charette, that the chapel + oratory / chaplaincy ensemble took on its facing arrangement characteristic of Briord.
Under Joseph Charette (1722-1792), the religious life of the estate was organised around these buildings. Joseph Charette was an aristocrat of the Enlightenment — his library of more than a thousand volumes bears witness to his openness to the authors of the century, Rousseau, Montesquieu, Voltaire — but also a châtelain mindful of the religious service of his house. In 1792, when tension became extreme, his private chaplain was Abbé Jean Bouchard, an unsworn priest — that is, refusing the oath to the Civil Constitution of the Clergy of 1790. His presence at the château, together with that of an Irish priest not subject to the oath invited to celebrate Mass, scandalised the sworn parish priest Fortineau, who on 25 February 1792 denounced a clandestine public Mass attended, he said, by 1,200 people.
Charette's arrest followed in the summer of 1792. The chaplain Bouchard was arrested too. He was among those in the drowning of 16 November 1793 — one of the tragic episodes of the executions of Nantes under the Terror. Joseph Charette, released on account of his state of health, had returned to his Nantes home, where he died on 17 October 1792. The memory of Abbé Bouchard has, since that date, been inscribed in the religious history of the estate.
After the death of Joseph Charette, the estate was placed under sequestration on 20 June 1793. The furniture was inventoried and then transported to Nantes. The chapel, like the whole estate, entered a period of silence. The deed of sale of 1798 mentions the "former chapel roofed with slate, one hundred and ten feet in length and breadth by eighteen in height" — dimensions that probably correspond to the Saint James chapel in the park.
Under the Dubois-Violette (1800-1833), Nantes merchants of mixed alliances (Protestant Möller, Catholic Charette), the chapel was not the object of notable investment. The Dubois-Violette were businessmen, turned towards colonial trade — the Fils de France and its voyages to China — not religious founders. Under the Pantin de La Guère (1833-1850), the chapel remained in use, but without major transformation.
Everything changed with the arrival of Michel-Adolphe Pelet de Lautrec, who married Mathilde Pantin de La Guère at Nantes on 17 June 1850 and brought to Briord a flamboyant, ultra-Catholic and ostentatious temperament. Under his impetus, the chapel was built — or enlarged with two aisles — and solemnly blessed on 15 June 1853. It was consecrated to Saint Germain and the Virgin. It is this building that one sees today in the park, to which later generations added various completions.
Pelet de Lautrec was a fervent Catholic whose devotion expressed itself in striking gestures. A legitimist officer who resigned in 1850, he returned to service in 1860-1861 to defend the Kingdom of the Two Sicilies at the siege of Gaeta, alongside King Francis II and Pope Pius IX. It was the pope who then gave him relics of Saints Peter and Paul and a notable fragment of the True Cross. But contrary to what tradition has sometimes suggested, these relics did not remain at Briord: Pelet de Lautrec donated them to the parish of Port-Saint-Père in 1862, as part of the project to rebuild the parish church, which he financed.
At the end of the 1870s, the chapel and the château of Briord were the setting of one of the most troubling episodes of their history: the Théotiste-Françoise Covarel affair. This young Savoyard seer, released from the Bassens asylum in 1877 thanks to Pelet de Lautrec's intervention, was installed at the château as the countess's chambermaid. As soon as Pelet de Lautrec had left to rejoin his regiment at Béziers on 10 April 1877, the apparitions began. According to the letters that reached the absent husband, the Virgin appeared to Théotiste in the countess's bedroom — and not in the chapel, as one might suppose. The visions evoked the salvation of France, the conversion of the Pelet de Lautrec son, the sale of the estate.
The affair gravely divided the couple. The countess, under the influence of Abbé Cloquet — former grand vicar of the schismatic bishop Vibert of Maurienne — gave credence to the visions. The viscount, furious, accused his wife of "harmful hallucinations". A legal separation was pronounced by the civil court of Paimbœuf on 12 April 1878. The chapel itself was not at the centre of the affair, but the general atmosphere of the estate — the reception of ecclesiastics, a climate of devotion, debates on the salvation of France — explains the countess's receptiveness to her servant's visions.
After the sale of the estate to Jean-Simon Voruz on 25 November 1885 for his minor grandson Jean-Baptiste Étienne, the chapel entered a more discreet period. Voruz, a Protestant, a member of the consistory of Nantes since 1847, did not remove the building. Jean-Baptiste Étienne, raised in the Catholic religion, maintained the use of the chapel. The sale expressly included "the furnishings of the chapel", which means that the building was in working order and contained its liturgical fittings.
During the sixty-four years in which Jean-Baptiste Étienne governed Briord (1885-1949), the chapel lived to the rhythm of the great family occasions and the ceremonies linked to the Briord Hunt — founded in 1892 and disbanded in 1937. Masses of Saint Hubert may have been celebrated there for the huntsmen, even if the available sources give no detailed description of them. Jean-Baptiste Étienne died not at the château, but at his town-house on the Rue Linné in Nantes on 22 October 1949. His posthumous appointment as Knight of the Legion of Honour is dated 30 August 1949.
In the decades following the death of Jean-Baptiste Étienne, the chapel went through a difficult period. In 2003, its condition was such that the owner of the time filed a demolition permit application as a safety measure. The veto of the services of the Regional Directorate of Cultural Affairs saved the building. The roof, however, collapsed completely; the stained-glass windows had already disappeared. Since 2021, under the new owner, the chapel has been the subject of a restoration programme aimed at restoring its integrity.
The building one sees today thus bears the memory of all these strata. The Charette armorial motif in the central part recalls the primitive 18th-century building, then dedicated to Saint James. The overall structure — with its two aisles — bears the hand of Pelet de Lautrec in 1853. The dedications — Saint Germain and the Virgin — are his. The whole is, like the château itself, the product of successive strata rather than of a single creation. This complexity is characteristic of Briord, where each century has left its mark on the preceding one.
