A distinctive feature of the hall is that, though it is small, it gives the impression of unfolding and of become wider, no matter where the viewer is standing. Also remarkable is the use of colour, the way white and brown are made to alternate. All the decoration is superimposed on the underlying wall, so that none of it is weight-bearing. The use of wood and plaster, for instance, for the capitals, does not make the structure heavier; in addition it plays an important role in that it minimizes the echo and creates a magnificent sound box.
