Origin and history

The Church of Notre-Dame du Roncier, located in Rostrenen in the Côtes-d'Armor (Bretagne), is a monument dating back to the early 14th century. From this primitive period there remain the cross of the transept, its lengths, as well as the side gate géminée opening on the south porch. The latter preserves in its lower part ten trilobed archatures, characteristic of the Gothic style, while its upper part, adorned with twelve Renaissance niches crowned with shells and separated by geometric pilasters, dates from the sixteenth century. The arms of Jehanne de Rosten and Alain de Rohan, visible on the arcades, attest to their patronage in the 14th century.

The church tower, erected between 1676 and 1678, marked a major reconstruction phase in the seventeenth century, as did the gables of the transept, the choir and the sacristy. The nave and the lower side were entirely rebuilt in 1888 according to the plans of architect Henri Guérin. Among the remarkable elements, three 18th-century altarpieces adorn the interior, while the lateral gate, classified as historical monuments by order of October 22, 1913, bears witness to the heritage value of the site. The west tower was added in 1776, complementing the architectural evolution of the building.

The church Notre-Dame du Roncier thus embodies almost five centuries of Breton religious and architectural history, mixing medieval, Renaissance and classical influences. Its southern porch, particularly emblematic, illustrates the transition between the flamboyant Gothic and Renaissance forms, while subsequent additions reflect the liturgical and aesthetic evolutions of the seventeenth and eighteenth centuries. The partial protection of 1913 underlines its importance in the heritage of Côtes-d'Armor, where it remains a place of worship and local memory.
