From the Town Hall, take the D187 towards Épaumesnil, then continue along the old Rouen road (D96). When you arrive in Épaumesnil, turn right, and continue straight ahead following the sign to Avesnes-Chaussoy (1.6 km).
On your left, in the forest, you will find the renovated site of the launch of the Second World War V1, with information boards.
Slightly further on, as you leave the site on the left: the 16th-18th century castle, built in brick and white stone with a 6-sided tower, crowned with a slate roof, stands elegantly in a haven of trees and lawns.
Retrace your footsteps to the cross. Continue along the road to Saint-Maulvis. Continue along Rue du Mauvais Pas, the Rue des Carons, down to the bottom: on the right, you will see the church. Return to the Town Hall down the stairs.
