Origin and history

The chapel of Mangolerian, also known as the Chapel of Mille Secours, is located at the place called Mangolerian, in the commune of Monterblanc (Morbihan, Brittany). Dated from the 3rd quarter of the 15th century, it was erected in 1463 according to the sources. It is distinguished by its rectangular architecture of 23.70 m by 9,90 m, reinforced by corner foothills and a slightly broken arched west entrance. Its flat bedside is pierced by a large gothic bay, while its bell, dated 1565, has messes and pilasters with capitals.

The chapel was built on the foundations of a Gallo-Roman villa, showing an ancient occupation of the site. It is surrounded by a square delimited by a wall mounted in 1970, when the entrance staircase was repositioned. The site also includes a house of the chaplain (XIXth century), a 16th century calvary brought back in 1980 from the hamlet of Mangoro, and a 17th century fountain. The chapel was listed as historical monuments on 10 January 2001.

The place was marked by the history of Chouannery: Mangolerian's fight took place there on 15 March 1794, opposing revolutionary forces against insurgents. Inside, the chapel preserves sculpted sandstones and a vault with wooden arches from the end of the 15th century, as well as 19th century painted panels on a blue background. These elements illustrate its architectural evolution and its role in local life.

The architectural complex, owned by the commune, reflects both the Breton religious heritage and the traces of the conflicts that marked the region. The chapel remains a testimony of cultural and religious practices from the late Middle Ages to the modern era, while integrating more recent redevelopments, such as the restoration of the bell tower in 1565 or the modifications of the nineteenth century.
