The rim round the fountain is an original piece from the 16th century; the basin consists of a slab of diagonally veined Carrara marble while the plate is of stark white statuary marble, where the water slides through with shimmering effect like a flame in the hearth.

The space around is elegant and sophisticated, ideal for passing a few moments of relaxation, or for having supper or lunch in the seasons of fine weather which the "Eternal City" so generously provides.
