Port of Castellammare di Stabia, Commercial port in Castellammare di Stabia, Italy

The Port of Castellammare di Stabia is a commercial facility divided into two main basins: Porto Davide for yachts up to 30 meters long, and a separate commercial harbor basin. The facility operates 210 berths with infrastructure for handling break bulk cargo, salt, and cereals.

The port was built centuries ago, and Castellammare di Stabia's first settlement grew along its waterfront. A maritime station, Castellammare Marittima, was later built inside the port and linked by a rail spur to the Torre Annunziata–Gragnano line, so grain and salt could be loaded directly onto trains. The port has since passed under the jurisdiction of the Port of Naples, with plans to convert the disused commercial zone into a cruise reception area.

The port's first urban nucleus grew along the harbour front, and the water still shapes local work: the northern zone near the Acqua della Madonna is used by small local fishing boats and modest trawlers. Ferries and hydrofoils leave from a small area facing the commercial zone entrance, bound for Capri via Sorrento and for Amalfi.

Visitors should know that this is an active commercial port where some areas may have restricted access due to ongoing operations. The best time to explore is during early morning or late afternoon hours when activity is lighter.

Since 2008, smaller cruise ships have docked here instead of Naples, and by 2019 the port was the only Italian port equipped to receive gigayachts between 50 and 100 metres long. The commercial area, with its disused grain and salt silos, is slated for conversion into a cruise passenger reception zone under the Port of Naples authority.
