Port Vell is a waterfront harbour in Barcelona, built as part of an urban renewal program prior to the 1992 Barcelona Olympics. Before this, it was a run-down area of empty warehouses, railroad yards, and factories. 16 million people visit the complex each year. A pedestrian walkway, Rambla de Mar, connects La Rambla to Port Vell. It incorporates a swing bridge, in order to allow ships to enter and exit the harbour.
