Two abbeys in Wisques will capture your attention: the one dedicated to St. Paul of the 15th century, and the one of Our Lady of the 19th century.
Get down the valley walking towards Esquerdes. It's the very place where an old gunpowder factory straddle the river, that flows into the North sea through a delta, located in Gravelines, where the water is canalised by Vauban's lock and "wateringues". Cross the wood of Esquerdes, and then the Chaussée Brunehaut. This one bear the name of the Austrasia queen who died there, people say, with her hair tied with the tail of her horse and dragged around so.
