 The soil in the cultivated areas has been identified as fine and pebble-free in an otherwise stony environment which indicates a sieving process (Ricetti could access and adapt materials located on the town dump nearby).The terraces were planted with a variety of edible and ornamental plants which demonstrates aesthetic as well as practical values.Ricetti collected, shifted, cut and placed thousands of cubic metres of stone to create the series of retaining walls around the ten identified terrraces and the extensive stairways that link the elements of the site.
