 Expansion of Naples to the west under the Spaniards in the 17th century and subsequent development under the Bourbons and then by the national Italian government between 1880 and 1915 gradually led to the incorporation of Mergellina into greater metropolitan Naples.Today it is still a fishing port but also an important secondary tourist harbor for hydrofoil traffic to the islands in the bay of Naples and to various tourist destinations along the Campanian coast.The port also serves as mooring for private pleasure craft.
