Mergellina is a coastal section of the city of Naples, Italy. It is located in the quartiere of Chiaia. It stands at the foot of the Posillipo Hill and faces the Castel dell'Ovo. The name derives from that of a shorebird called "mergoglino". There is some doubt amongst the locals as to the origin of the name "Mergellina". The main opinion is that it is a corruption of "Mare Giallo" which refers to when the sea turned yellow due to floating tufa rock dust following a volcanic eruption many centuries ago.(Wikipedia)
