Origin and history

The chapel of Locmaria, located in Rostenen in the Côtes d'Armor, is a religious building whose origins date back to at least the fourteenth century. Fenestrages of this period, re-used in the nave and gable of the chapel, attest to the existence of a first building, probably damaged during the war of succession of the Duchy of Brittany. These architectural elements suggest an ancient foundation, although the most visible material traces date from later reconstructions.

At the beginning of the 15th century, the chapel was completely rebuilt, adopting a simple rectangular plan with a lateral chapel south of the choir. This major reshuffle probably follows the destruction of the previous century's conflicts. The building today preserves this medieval structure, marked by defensive or liturgical elements characteristic of the era, although the sources do not specify the exact motivations for this reconstruction.

The 18th century brought notable changes, including the addition of a porch decorated with a late ivy vault, decorated with a dove symbolizing the Holy Spirit. This porch, along with the adjacent gable, dates back to this period, as did an arrow that initially overcame the tower, erected in 1720 but collapsed in 1877. These arrangements reflect a desire for Baroque beautification, typical of the Breton churches of the modern era.

In the 19th century, a sacristy was added to the north of the chapel, supplementing liturgical spaces. The building, formerly the trevial church of Plouguernével (or Plouguernevez according to the sources), is finally classified as historical monuments by order of 16 June 1964. This protection concerns the entire chapel, with the exception of the upper part of the bell tower, and underlines its heritage importance.

The chapel of Locmaria thus illustrates centuries of Breton religious and architectural history, from medieval conflicts to the beautifications of modern times. Its sober plan and its late decorative elements bear witness to the stylistic evolutions and community needs, from the Middle Ages to the contemporary era.
