Fontana dell'Esedra, Public fountain in Mostra d'Oltremare, Naples, Italy.

The Fontana dell'Esedra is the largest fountain in Naples, occupying 900 square metres within the Mostra d'Oltremare complex. It has 76 exedra basins, 1,300 brass and bronze nozzles, and 12 cascading fountains, with jets that can reach 40 metres. Its ceramic decoration is by Giuseppe Macedonio, and it is surrounded by 800 tall pines and holm oaks.

The fountain was designed by architects Carlo Cocchia and Luigi Piccinato in 1938 and opened in 1940 as part of an exhibition project. It reflects the urban development ambitions of Naples during that era.

The fountain's inauguration featured a dedicated symphony called Fontane d'Oltremare, combining synchronized water displays with orchestral music.

The fountain stands in the Mostra d'Oltremare complex in Naples, reachable by the Cumana railway at Mostra station. As of May 2025 it is inactive and largely abandoned, so expect dry basins rather than water displays. The 900-square-metre structure is ringed by 800 tall pines and holm oaks, which give shade while you walk around it.

Eight hundred colored projectors illuminate 4000 cubic meters of water, creating synchronized displays among seventy-six cascading basins.
