Marina Port neighborhood is around the current Paseo de la Zona Franca next to the harbor.
The Port of Barcelona has a 2000-year history and great contemporary commercial importance as one of Europe’s ports in the Mediterranean, as well as Catalonia‘s largest port, tying with Tarragona. It is divided into three zones: Port Vell (the Old Port), the commercial/industrial port and the logistics port (Barcelona Free Port).
The Port Vell area comprises two marinas or yacht harbors, a fishing port, a maritime station for ferries travelling to the Balearic Islands and other destinations in the Mediterranean and other stations or landing areas for cruise ships, and it abuts the industrial port.
