A small village where you can eat and stay. There is a beautiful fortified church dedicated to Saint Martin and a pond ideal for sports activities.

The Marais de la Souche is a vast peat bog which offers a remarkable diversity of habitats and fauna. If you want to explore this natural site, you can hike from the Notre-Dame de Liesse basilica and cross the woods, fields and marshes. You will see many birds, plants and insects there, as well as some historical monuments.

The church of Burelles, close to those of Gronard and Prisces

The village of Pierrepont already stands out - even on comments on the internet - by the presence of a bakery and a bar. This compared to the other villages in the region that only house a church and a municipal school. We also noticed two beautiful scenes in the form of a letterbox incorporated into a bicycle and a fisherman on the other. The cross next to the Visser is also listed as a monument on Wikipedia.
