Section of Appennino. Inside you will find a network of grottoes, their walls studded with shells, corals, pearls and crystals, and painted with frescoes of muscled men mining precious ores. In this way, Appennino is both mountains and abysses. You enter not only the belly of a garden giant but also down into the belly of the earth. There were also two working fountains, one of which portrayed Thetis, and located in his head is a chamber for a small orchestra.
