You walk on the green avenue. 40 km long, this route echoes a long Franco-British history. In 1873, a railway was built to provide access between London and Paris via the Dieppe - Newhaven shipping line. This connection is still relevant, no longer by train, but by bike! At this point, you straddle the Béthune. This river has its source in the town of Gaillefontaine at an altitude of 205m. After a journey of 65 km, it joins the Varenne then the Eaulne at Arques-la-Bataille where their confluence creates the Arques.

The meeting fountain, located near the church and opposite the presbytery (18th century), is a small square equipped with benches and a drinking water point. We owe this fountain to the Brayon ceramists Jacques and Juliette Damville.
