The layout of the park is fairly schematic. The most obvious element is the long straight road of cypress trees that start from the entrance to San Donato Park across Negri. Along the way, the sculptural complex, consisting of about 200 human figures, is developing in real size, sculpting a theater and a kind of cemetery inside hollow walls in the meadow; the work, carried out between 1974 and 1984 by Nicolas Zamboni, is certainly the most important artistic intervention ever undertaken.
