This piazza gives entrance to a building or set of buildings whose every detail challenges the eye.

Twelve pillars of snow-white wood sheathed in part with bronze, arranged in four rows, make, as it were, the bones of the structure.

The space between the centre columns lies open.

The other triplets are webbed in the middle and connected, on the sides and front, by grilles of wood and bronze forming on the outside a couple of embrasures on either hand the entrance in which stand the guardian Nio, two colossal demons, Gog and Magog.

Instead of capitals, a frieze bristling with Chinese lions protects the top of the pillars.
