Église Saint-Cerneuf de Billom, Medieval church in Billom, France.

Église Saint-Cerneuf de Billom is a church building that features three Gothic naves, a Romanesque crypt, and an ambulatory with radiating chapels of pentagonal shape. The structure shows a blend of architectural styles that developed across different periods of construction.

Construction of the church began in the late 11th century, but the structure underwent major changes during the 13th century when Gothic modifications replaced the original design. These building phases reflect changing architectural ideas and religious needs of their time.

The church keeps a wooden statue of Saint Serenus of Sirmium, shown in a short tunic and cloak holding a martyr's palm and a spade, since he is the patron saint of gardeners. The parish was originally dedicated to the Virgin Mary and was one of four parishes in Billom, alongside Saint-Loup, Saint-Michel and Saint-Saturnin.

The building is protected as a historical monument and remains open to visitors during regular hours so you can explore the interior spaces and architectural details. Plan to spend time wandering through the different areas including the crypt and chapels at your own pace.

Gilles Aycelin, Archbishop of Rouen, died in Avignon on 23 June 1318 and was buried on 17 August 1318 in the Rosary Chapel he had founded. His Volvic stone tomb, topped by a canopy with Saint Peter and Saint Paul on the jambs, is the only one to survive the Revolution; its base shows a cardinal, two bishops, an abbess and four clergy, likely his relatives.
