The Forcone Basin is considered by some to be the masterpiece of Zanobi del Rosso, who is also responsible for the Kaffeehaus. The basin itself was executed in 1777-78, while the terraces surrounding it are from the 17th century. Here originally was a nursery for the gardens. The pond collects water from an aqueduct and the water is used to irrigate the gardens. In the middle of the pond is a bronze statue of Neptune by Stoldo Lorenzi, dating from 1571.
