The Château d'Happlaincourt, a medieval castle, dates from the 13th century and was originally a fortified structure with a square floor plan, surrounded by water. During the First World War, the castle was largely destroyed, leaving only ruins today. Historically, it played a role in the Catholic League in the 16th century, when Jacques d'Humières drew up a manifesto there to restore the Catholic religion.

The Frize mountain belvedere reveals a striking view of the meanders of the Somme, in a peaceful setting that contrasts with its past marked by the battles of the First World War. Traces of this history are still visible in the trenches and shell impacts. Mentioned by Blaise Cendrars, this land rich in history today offers visitors an exceptional panorama of a landscape of marshes and ponds.
