The large square between the modern fountain and the Madonna della Riva Sanctuary has had various names over the centuries.
Known as Piazza del Lago in 1770, it was then named after Ferdinando I; after Italy was united it was called Piazza della Riva, Piazza del Lago and Piazza Stazzona; since 1883 it has been named after Giuseppe Garibaldi.
Excavations conducted in 2005 under the pavement led to the discovery here of Roman buildings.
