Abbey of Saint-Martin, Pontoise

The Abbey of Saint-Martin is a Benedictine monastery in Pontoise, situated close to the Oise River. The building displays Romanesque features with substantial stone walls and detailed religious carvings throughout.

The monastery was founded in the first half of the 11th century and became important after its first abbot, Walter, was declared a saint. This made it a significant pilgrimage destination.

The monks who lived here during the 17th century turned this place into a center for study and debate. Their work in theology and philosophy shaped intellectual life in the region.

The site is now home to a school and can be visited with advance arrangements and guided tours. Visitors should check ahead about access and visiting options.

The tomb of Saint Walter remains inside the abbey church and draws visitors seeking spiritual connection. Few people know this shrine is one of the oldest religious reliquaries still preserved in the area.
