Origin and history

The Chapel of the True Cross, also known as the Chapel of Langroës, is located at the place called Langroix, on the town of Plumergat, in the department of Morbihan (British). According to a sandstone engraved on its northern flank, its construction dates back to 1562, making it an architectural testimony of the Breton Renaissance. Its designation as historic monuments, effective since October 21, 1925, underscores its heritage value. The chapel benefited from a restoration in 1954, preserving its characteristic elements such as flamboyant snout windows or adorned larmies.

The building is distinguished by its granite façade, its basket-ringed doors framed with pinnacle pilasters, and a spread coat of arms supported by two lions above the entrance. The choir, of polygonal shape, is pierced by an oculus at the bedside, while some windows in third-point, partially blocked, illustrate the modifications experienced over the centuries. These details reflect both the late Gothic influence and the local adaptations, typical of the Breton chapels of that time.

Owned by the town of Plumergat, the chapel of Langroës embodies the central role of places of worship in the Breton rural life of the 16th and 17th centuries. These buildings served not only religious practice, but also community landmarks, often linked to local legends or pilgrimages. Their architecture, combining religious symbols and decorative motifs, bears witness to the craftsmanship of the period and the importance of granite, a dominant material in the region.

The available sources (Wikipedia, Monumentum) confirm its status as a protected historical monument, as well as its precise location at 16 Langroix, 56400 Plumergat. The protected elements, listed under cadastral reference XD 6, include the nave and polygonal choir, characteristic of the Breton chapels of this period. The absence of any mention of specific sponsors or artists in the sources limits the knowledge of its social history, but its heritage inscription guarantees its preservation for future generations.
