Fontana del dio Nettuno, Marble fountain in Piazza Giuseppe Mazzini, Nettuno, Italy.

The Fountain of Neptune is a marble sculpture in Piazza Giuseppe Mazzini depicting the sea god in a shell chariot drawn by horses. The piece sits above a large water basin that anchors the entire composition.

The original travertine statue was sculpted by Ottavio De Angelis in 1882 to commemorate the opening of the Albano-Nettuno railway line. Between 1949 and 1950, local artist Randolfo Belleudi added the shell chariot and horses, transforming the initial design.

The city of Nettuno takes its name from the sea god Neptune, and the fountain bearing his image stands as the town's symbol. Before World War II the statue served as a horse trough in Piazza del Mercato, and today it remains a gathering point in Piazza Mazzini.

The fountain sits in Piazza Giuseppe Mazzini at the town center and is easy to reach on foot from most locations. The square is freely accessible and offers space to walk around and view the sculpture from different angles.

The travertine Neptune was carved by Ottavio De Angelis and donated to the town in 1882 for the opening of the Albano-Nettuno railway. The shell and horses by Randolfo Belleudi were only added in 1949-1950, and the three fish spraying water toward the shell probably date from the 1960s.
