Between the farm and the castle, above the carpentry's shop extends the Godefroy de Bouillon premises.

In this building one finds mainly the rooms of the boys at a rate of one per escouade. They are decorated and maintained by them and each one puts a point of honor to arrange its own affaires as nicely as possible.

On the lower floor, one finds the museum of the military chaplains and that of the war 14-18.

On the ground floor, a large room is especially used to accomodate the various meetings which take place at Riaumont (preparation of Fires of the Saint Jean). The welcome capabilities of Riaumont makes it a place of appointment for many scouts but also of other organizations. We had the visit of the Anisetiers regularly - traditionally for the Saint Nicholas feast -, certain chapters of the Paris to Chartres pilgrimage at Pentecost, the Montjoie-Saint-Denis Choir and of many others.
