The castle is almost invisible from the towpath. Good that the highlight is positioned correctly, otherwise you will definitely miss it.

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 town of Péronne is truly charming and well worth a visit. The Somme River forms natural ponds that surround the city, giving it an undeniable appeal. Its old town is located on a small hill overlooking the entire area.
