The fish ponds are one of the most ancient and evocative elements of the park. Pictures of the 17th century show that they already existed at that time and were the ideal background for banquets and parties.
Once left the parterre to the north of the Villa, visitors can walk into the park following a path lined, on both sides, with lime trees (Tilia), and bordering the first arm of the fish pond. The latter bends abruptly to the north and in this section the trees lining the path are mainly ash trees (Fraxinus) and some black alders (Alnus glutinosa), which replaced the original lime trees. Near the corner of the fish pond, there are two little waterfalls decorated with stones and rocks, which bordered the sides of a slope descending to a water hole.

Some huge masks and ruins of statues are placed on the two sides of the fish pond path. Probably this stone material would have been used for the decorations of the semicircular colonnade that, according to Paolo Camerini's project, would have closed the semicircular square in front of the Villa, but the project was never carried out. A canal coming out of the fish pond feeds the lake nearby.
