Royal Gardens

Rock Garden and Belvedere

Designed by Piermarini at the end of the 18th century, the grotto-nymphaeum had an elaborate architectural façade and a terrace-belvedere with balustrade which provided a scenic view of the tree-lined avenue extending south along the northern prospect of the building, as far as the Lambro. Valuable evidence of the original layout of this structure, which was later denuded of its stone covering, appears in two paintings by Martin Knoller, one of which portrays with precision the prospect of the grotto-nymphaeum and waterfall.
