The citadel at Doullens is the oldest fortified place in France, built before Vauban was even born. It was used for five centuries, first as a fortress, then as a prison. Today, Somme Patrimoine's cultural project aims to share the citadel's history with as many people as possible, as well as raising awareness of the need to preserve and conserve built heritage.
Visit the Doullens citadel with a cultural mediator and discover the stages in its construction and the different uses to which it has been put since the 16th century: landscape readings, a walk on the ramparts and discovery of the citadel and prison buildings: solitary confinement, bunker, counter-mine galleries, etc.
