Abbaye bénédictine

The Benedictine Abbey of Saint-Austremoine is a former monastic church in Issoire, in the Puy-de-Dôme department of the Auvergne-Rhône-Alpes region. It ranks among the five great Romanesque churches of Auvergne, alongside Notre-Dame-du-Port in Clermont-Ferrand, the church of Orcival, Saint-Nectaire and Saint-Saturnin — and it is the largest of the group, stretching some 65 metres in length, rising 18 metres to the vault and 23 metres beneath its central tower.

How did the abbey come to be built in Issoire?

The monastery's origins go back to the ninth century. According to local tradition, in 816 Benedictine monks from the abbey of Charroux in Poitou fled Norman raids and took refuge near Saint-Yvoine. One of them, a monk named Gislebert, made his way to Issoire and set about rebuilding an older, already ruined monastery dedicated to Saint Austremoine, traditionally venerated as the first bishop of Clermont and an early evangelist of Auvergne. The church visitors see today, however, was raised much later, at the turn of the eleventh and twelfth centuries, taking its final form around 1130.

What makes the architecture distinctly Auvergnat?

The church was built from arkose, a golden local sandstone quarried at nearby Montpeyroux, which gives the walls their warm colour. Its layout follows the classic pilgrimage-church plan: an apse ringed by an ambulatory and radiating chapels, standing above a crypt. Over the crossing rises a massive rectangular block topped by a bell tower — the vertical, layered silhouette that defines Auvergne's Romanesque churches. Two sloping roofs wrap around the base of the tower, reinforcing the sense of volumes stacked progressively skyward.

What decorates the east end of the church?

The chevet is the building's most ornate feature: slender colonnettes, carved capitals, corbels, and two-tone stone mosaics arranged in geometric patterns cover its surface. Set among them are thirteen carved medallions depicting the twelve signs of the zodiac, a motif read in the medieval period as a symbol of the changing seasons and, by extension, of divine order governing time.

What is inside the church?

Beneath the choir lies one of the finest crypts in the region, holding a twelfth-century reliquary of Saint Austremoine. Inside the nave and choir, the eye is drawn to bold polychrome decoration dating from the thirteenth century, restored in its present form between 1857 and 1860 by the painter Anatole Dauvergne. The palette leans toward reds and browns, and the work was executed as true fresco, painted directly onto wet plaster — a technique rarely used in France, where the dry "a secco" method was far more common. Separately, the historiated capitals in the choir, thought to be the work of sculptors from Languedoc, narrate a cycle of scenes running from Holy Thursday to Easter Sunday.

The abbey church has been a protected historic monument since 1840, placing it among the very first buildings to receive that status in France.
