Origin and history

The Orvaire de Port-Arthur is a religious monument located at Port-Arthur in the commune of Pluméliau (Morbihan, Brittany). Dated in the 17th century, it is distinguished by its altar-shaped architecture, decorated with carved motifs such as angels, a lamb symbolizing Christ, and hermines – emblems of Brittany. The cask, treated in the Corinthian column, supports a trinitarian cross representing Christ between the Virgin and Saint John, surmounted by God the Father and the Holy Spirit in the form of a dove. This calvary illustrates Breton sacred art of modern times, mixing religious symbolism and local elements.

Ranked a Historic Monument since 29 March 1935, the Calvary was moved after its protection, as evidenced by the photographic archives of the 1950s. Its curved base, decorated with clusters of grapes and angelot heads, as well as its knot adorned with overturned hearts, reflect a precise craftsmanship. A partial inscription (letter B) suggests a possible attribution to the Cabedoche brothers, artisans active in the region in the 19th century, although the initial dating remains the 17th century. Its current location, on the edge of an old path between Baud and Pontivy, highlights its historical role as a spiritual and cultural landmark.

The structure combines classical architectural elements (corinthian column, volutes) and Christian symbols (lamb with seven seals, Franciscan cordon), typical of Breton calvaries. The mention of the first half of the 19th century for some sources might indicate a restoration or subsequent reinterpretation, but the original work dates back to the 17th century. The communal property and its accessibility make it a living heritage, linked to local history and past religious practices.
