Here was located the eastern gate of the medieval walls of the city. This gate, demolished in the early XIX century, at the end of the 1400s was called Porta Pica, a name retained by the modern street. Said name was given to the construction because between the XV and XVI centuries it was decorated with frescoes by artists from Bergamo, such as Simone da Averara and Bartolomeo Cabrini.
The fountain was built symmetrically to the large vault covering the gate.
