Grotta
Between the Tower and the Serra, Jappelli had created an artificial Grotto, undoubtedly one of the most unique attractions of the Villa, already created by the Venetian architect in the garden of Saonara called L'antro dei Templari.
Here too, as in Saonara, and as was often the case in landscape gardens beyond the Alps, above the Grotto there were fake ruins of a Medieval Castle and Tower, still perfectly preserved today.
Among these fake ruins and fake stalactites is the main entrance to the Grotto, surmounted by the inscription Nymphae Loci... the place of the Nymph. Inside the cave, two small artificial lakes have been reactivated, supplied by small waterfalls, while it has not been possible to restore the footbridges that ran halfway up the cave, but of which there are still evident signs in the walls.
Part of the cave was demolished in 1908 because it was considered unsafe, but it is still perfectly legible thanks to recent restoration work and the lighting project.
