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 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.

Whether on the Somme or on the canals: driving on the water is always pleasant. Water-rich area...

The Etangs de la Barette are a natural site of approximately 40 hectares located in the communes of Corbie and Vaux-sur-Somme. The site is made up of large artificial ponds which were dug by the monks of Corbie Abbey to serve as a fishpond, then used for peat extraction in the 19th century. You can enjoy the view of the water and wetlands, and observe the diverse flora and fauna that populate the site. You will also be able to see the Blue Fountains, water springs that appear blue due to the reflection of sunlight on the chalky bottom. The Etangs de la Barette are an ideal destination for nature lovers who wish to discover a rich and preserved environment.
