In the heart of the village, you will not be able to remain indifferent in front of the former pleasure residence of the bishops of Soissons. It lies in the shadow of an imposing 14th century keep that dominates the landscape from its 45 meters high.
Victor Hugo, passing through the region is also subjugated by the beauty of this site and describes it to his wife:

“Two leagues from Soissons, in a charming valley, an admirable châtelet is still perfectly habitable. It is the most striking dwelling that you can imagine.”

Enjoy privileged moments of sharing and complicity with your family in the shadow of this fairy-tale dungeon. Climb its steps to enjoy the exceptional panorama offered by its roof terrace.

Wander around again in its immense arboretum that brings together species from around the world.

You’ll have understood, the Septmonts Keep Park is the ideal place to spend time with the family! A picnic, a balloon and that’s it!”
