Until 1812 the Neapolitan Piazza del Carmine, more commonly known as Piazza Mercato, housed this splendid monument, known as the Dolphin Fountain. From this fountain, it is said that Masaniello used to crowd the crowds!
In that year it was purchased by the municipality of Cerreto Sannita, in the Benevento area, which was the first county of the Normans and in the fifteenth century it became a feud of the Carafa di Maddaloni family.
Today the fountain is situated in the square of San Martino in Cerretese, where the church of the same name stands and in front of the ex-feudal prison-palazzo del Genio complex. It is made of worked limestone in the lower part and lava stone in the upper part. Water gushes from the mouths of the four dolphins and a decorative cone emerges in the centre. The fountain was purchased by the municipal administration of Cerretese in 1812, in particular the parts in lava stone (the dolphins and the central cone), while the rest in limestone was added the following year in 1813, when the mason Biagio Ciccarelli was assigned the work for the remaking of the fountain of S. Martino. Originally it was placed in the northern part of the square but in the first half of the 20th century it was moved to the southern part, where it is today, to make way for the first war memorial.
