Discover the Château Fort de Guise, an exceptional site where nearly 1,000 years of military and architectural history can be seen. Dominated by its medieval keep, the castle became one of the largest bastioned strongholds in northern Europe in the 16th century, under the impetus of the Dukes of Guise, to the point of attracting the attention of Vauban.

Over the centuries, the monument also went through dark times: bombed during the First World War, it almost disappeared forever. The history of the castle changed in 1952 when Maurice Duton founded the Club du Vieux Manoir, a youth movement committed to serving young people and heritage. Thanks to this mobilisation, the site came back to life and continues to be preserved and brought to life by enthusiasts today.

Your visit is completely self-guided, on the opening days and during the opening times. Follow a simple route with numbers to look for and signs at each stopping point. Explore the keep and its three levels, then continue to the bastions, casemates, and underground passages to immerse yourself in defensive engineering. Don't miss the archaeological museum, the Cellier de l'Arsenal, and enjoy a beautiful vantage point over the city and the Familistère. An authentic experience, perfect for history buffs and families looking to explore at their own pace.
