Abbey of Saint-Acheul

The Abbey of Saint-Acheul is a classical stone church with a crypt situated beneath it containing ancient tombs and carved reliefs spanning multiple periods. The underground chamber remains accessible to visitors interested in exploring the layers of history carved into the walls.

Bishop Rorico founded the monastery in 1085 as a religious community serving Amiens and surrounding lands. The French Revolution brought its monastic life to an end in 1790, transforming the site's purpose.

The church preserves the memory of Saint Firmin, the first Bishop of Amiens, through carved stone reliefs from the 15th century depicting scenes from his life. These artworks allow visitors to follow the saint's story directly on the walls.

The former monastery buildings now house a private secondary school, while the church itself remains open to visitors as a functioning parish church. Before visiting, check opening hours as the site may have restricted access times for the crypt and main church spaces.

The crypt was discovered by chance in 1697 during altar work, revealing multiple ancient sarcophagi arranged within its stone walls. Local monks identified one as the tomb of Saint Firmin, which brought pilgrims seeking connection to the early saint.
