Situated on the banks of the Authie river, Willencourt boasts over 800 years of history. The village boasts an interesting architectural and natural heritage, including a wattle-and-daub school hall (one of the few in the département), an 18th-century chapel and a marshland linked to the history of its Royal Abbey. Willencourt offers a variety of landscapes that testify to its attachment to its heritage and respect for diversity. To welcome visitors to the village in a pleasant setting, the commune and its residents are very active in the flowering of the village, which has earned Willencourt several awards, including the silver medal for villages in bloom. The "Village Patrimoine" trail allows visitors to stroll around and discover the heritage of this peaceful village, particularly from the magnificent viewpoint overlooking the Authie valley, and to take advantage of the hiking and canoeing routes in the surrounding area.
