Given its large size, the interior of the Chantilly stables remind of religious architecture. On either side of the axial riding area, the two large naves can accommodate up to 140 horses. 11.60 meters wide, they are covered by a stone vault that rises to some 14 meters above the ground. The two large cradles are punctuated by arcs-doubleaux (transverse arches) forming numerous bays lit by tall windows providing a soft light which itself calms the horses and highlights the architecture. The decor consists of sculptures of deer busts placed on a cartouche arranged at the start of each arc-doubleau. The original furniture has been replaced by a system blending stalls and boxes.
