The religious complex had been built on the ruins of a church built in 1580 in honor of Our Lady of Porto Salvo precisely. This original construction had then been demolished about two hundred years later to make way for the shipyards of Castellammare di Stabia. Thanks to its properties, the water of the Madonna maintains its organoleptic characteristics unchanged over time, which is why it was used in the past by sailors about to embark on long voyages, taking it directly from the spring that also overlooked the sea. Precisely because of its use, it was also called sailors' water. In 2014, the taps of the Madonna water and the sour water were closed for several months due to numerous reports regarding the presence of polluting residues found in the fountains on Duilio Street. Following analyses and maintenance work commissioned by the city to the pipes, it was once again possible to enjoy these special waters still considered among the healthiest in the world.
