This is a living exhibition, which means that it changes over time. New works join the collection of sculptures every year. On the other hand, some of the works designed by their creators to be short-lived - and made of straw, hay, leaves, paper or flowers - disappear to be replaced by new works.
The route comprises three loops. One route encircles the village of Séprais itself. The second loop is larger and runs along farm tracks across open fields and pastures, descending to the school at Boécourt, one to the right and the other to the left of the main road. The full route is about 3 km long.
