This square took its name from the naked child in the fountain, because of its dark color, as the sculpture was made of cast iron. The Negrito fountain, from 1850, was the first public drinking water fountain installed in Valencia.

In the installation of drinking water in Valencia, we must highlight Canon Mariano Liñán, professor of History and Arabic Language at the University of Valencia, who died in 1844. Liñán bequeathed part of his assets (55,000 duros) for this end.
