Abbaye de Selincourt, Medieval abbey in Hornoy-le-Bourg, France.

The Abbaye de Selincourt was a Premonstratensian abbey founded in 1130 in what is now Hornoy-le-Bourg. Its church, about 75 metres long, had a transept and a choir surrounded by nine radiating chapels. The abbey was destroyed after the Revolution; today only fragments remain, and the adjacent farm building has a steep slate roof, a small white ridge turret and a light stone wall behind a white metal fence.

The abbey was founded in 1130 when local nobility provided land and monks established their community there. Over the following centuries it underwent changes in its religious leadership and structure before eventually being abandoned.

The abbey served as a pilgrimage destination, drawing visitors who came seeking spiritual connection and healing through sacred relics housed here. This role shaped how the surrounding community organized itself around religious observance and celebration.

Visiting the site requires planning since the ruins are scattered across private land and not always open to the public. It is wise to check ahead or contact the local community before planning a visit to understand access conditions.

The original abbey church was one of the largest religious structures in the region by its length, rivaling many well-known places of worship. Today only foundation remnants and architectural fragments hint at the former scale of this impressive building.
