Ste-Onenne

Ste-Onenne is a parish church in Tréhorenteuc featuring colorful mosaics by Isidore Odorico and stained glass windows depicting biblical narratives and Arthurian themes. The interior displays a variety of artistic elements integrated throughout different areas of the structure.

The site originates from the 7th century, and the building visible today was completed in 1962. This completion resulted from contributions by multiple artists over an extended period, notably including Henri Uzureau.

The stained glass tells stories that blend Christian faith with local Breton traditions, showing scenes from Saint Onenne's life within regional landscapes. These images reflect how deeply the place is woven into the community's identity and daily customs.

The church interior is open for visitors to explore, and the nearby Saint Onenne fountain is also worth visiting. A traditional procession takes place annually on September 29th, which brings the community together for celebration.

The building holds the only known representations of Saint Onenne, a local Breton saint associated with geese and ducks, displayed across six stained glass panels. This rare depiction makes the place a singular witness to her memory.
