They are of great value not only from a naturalistic, but also from a historical point of view. They still house centuries-old specimens of Japanese Cedar, Port Orford Cedar, Incense-cedar, and a 140-year old Sequoia. As far as the historical aspects are concerned, it is necessary to mention the Romanesque-style Baptistry and the adjacent cupelled boulder with Celtic engravings. Near the boulder, at the shadow of a wonderful cedar specimen you can admire a small lake, which seems a reproduction of Lago Maggiore.
