Duke Luigi Silvestro Camerini visited Ischia in 1946. He was a humanist and traveller and was looking for a place to create a park which would give reign to his passion for botany. The charm of the place and its surprising similarity to the Bay of Negombo, which he had seen and admired in Ceylon, persuaded him to choose the San Montano Bay. Here nature finds one of its strongest expressions in the thermal springs, proof of the volcanic history of the island, and still used according to traditions which have their roots in the classical age. The present aspect of the park owes much to the passionate intervention of the landscape architect Ermanno Casasco. His task was to create a garden strongly linked to the millenary culture of the site, but full of surprises and unexpected solutions. From 1998 Casasco placed important contemporary sculptures in the landscape of the park: “Arc-en-ciel” and ''Riva dei mari'' by Arnaldo Pomodoro, “Strale per il Negombo” by Lucio del Pezzo, “Gli occhi di Nesti e di Neri” by Laura Panno, “Volo” by Giuseppe Maraniello, ''Incontri'' by Simona Uberto and ''Sprigionamenti'' by Gianfranco Pardi.
The landscape in the garden is integrated with magnificent plants brought from Australia, Japan, South Africa and Brazil. There are fine specimens of Orbea variegata, Hakea, Encephalartos, Macrozamia, Cycas media, Dasylirion, Erythrina, Schinus terebindiflora, a monumental Ficus magnolioides and Eucalyptus ficifolia. The site still has age-old vestiges. In fact the necropolis of ancient Pithecusa was in San Montano Bay, one of the oldest Greek settlements in the West: around 770 B.C. the Eubei landed here, attracted by the sheltered position of the bay which offered refuge from winds and high seas.
