The Sebeto Fountain, located in Largo Sermoneta, was built in 1635 at the behest of the viceroy Emanuele Zunica and Fonseca, on a project by Cosimo Fanzago; the execution of the work was instead entrusted to his son Carlo Fanzago. Its original location was at the end of the Gusmana road, later called salita del Gigante (today via Cesario Console), leaning against a wall overlooking the arsenal below and positioned so as to face via Santa Lucia. In 1900 the fountain was dismantled and only in 1939 was it rebuilt in its present location, after the filling of the final stretch of Via Caracciolo was completed in the 1930s. The base of the fountain is all in piperno; the upper part is composed of three marble basins, of which the central one is the biggest and projecting one. On this stand two sea monsters from whose mouths water gushes out. The relief sculpture is situated in the centre and is represented by an old man, symbolizing the river Sebeto, the ancient waterway that flowed in the heart of the city. The two tritons at the sides of the fountain have little buccine on their shoulders that throw water into the side pools. To complete the fountain there is a plaque, surmounted by the three coats of arms of the Viceroy, the King of Spain and the city of Naples.
