Since 1988 the landscape designer Ermanno Casasco was in charge of the work, whose main commitment was to establish a visual continuity within the garden and develop new areas.
Commitment certainly completed and still today a constant “work in progress”. Hence the introduction of Mediterranean plants that were not present (or that had not survived) such as myrtle, olive tree, cork, but also, consistently with the original idea of a botanical park, the planting of new Australian or American essences, perfectly integrated into the whole (Metrosideros, Malaleuca, Macrozamia, Erytrina, etc.etc). And here, from a strictly architectural point of view, the recovery of the terraces, the dry stone walls, the central staircase, the insertion of water falls on the cliffs and the creation of new thermal experiences rather than trivial pools (the Labyrinth, Maya , the Templar, Onphalos, Nesti). Last but not least, the introduction of an "artistic" path into the landscape with the installation of numerous works of contemporary art starting with the large ceramic arch by Arnaldo Pomodoro "Arc-en-ciel" and the work "Riva dei Mari". Il Volo, a bronze work by Giuseppe Maraniello. The "Strale" by Lucio del Pezzo, "The eyes of Neri and Nesti" by Laura Panno, "Sprigionamenti" by Gianfranco Pardi, "Incontri" by Simona Uberto.
One of the strengths of Negombo is that this landscape cannot be separated from the practical function of the place. After all, the exploitation of the thermal baths for medical and health purposes is, as we all know, ancient history. The Romans already knew and frequented these places, where stood villas and gardens of great beauty. With ups and downs, over the centuries the spas were not completely abandoned and were rediscovered, as mentioned, at the beginning of the century, in conjunction with the enhancement of bathing.
