Piazza Mastai Fountain Rome
Both the fountain and the Manifattura, a building in the Piazza Mastai, were designed by the architect Antonio Sarti.
A second architect, Andrea Busiri Vici, was responsible for the fountain’s actual construction, which consists of an octagonal vessel on three steps.
The coat-of-arms of Pope Mattei is depicted on the monument and in its center there is another basin on a pedestal held high by 4 dolphins. On top of that vessel 4 lion’s heads spout water.
