The Barcelona pier is the south-west boundary between the Port Vell area (port transformed into an urban space) and the industrial port. The pier, 630 by 170 metres, is currently used by cruise lines and regular lines with the Balearic Islands. The dimensions and design of the promenade are in relation to the geometry of the World Trade Center building, located at one end of the pier, and the underground car park.
The WTCB is a large volume of four buildings with an inverted frustoconical envelope. A plinth formed by two passenger terminals frames the tower of the Montjuïc cable car, one of the landscape landmarks of the port.
A platform connects the new buildings with the city. The central promenade reserved for pedestrians is framed by the roads where the vehicles traveling to the WTCB and the parking ramps travel. At the urban end of the pier, an elliptical roundabout connects to the city's pedestrian and road circuit. In order to filter the presence of the large building in relation to the pier, the promenade tries to relate to the port's landscape context.
The granite pavement is laid out in transversal strips, connecting the central promenade and the side sidewalks, and is structured by means of a grid of slats and parterres that make up several areas: one in the centre, with a linear route, and two on the sides, of a more static character.
The vegetation and the lighting are drawn in two frames that articulate the platform. There is a main plot of medium-sized trees, gleditsias triacanthos plants from every 8 and 11 m, with date palms here and there. At the ends of the promenade, the tall casuarinas mingle with the palm trees according to a syncopated rhythm. Finally, there is a regular arrangement of small trees, parkinsonia aculeata, which introduce areas of shade and changing colours throughout the year. The lighting elements (stainless steel columns with angled arms that project light in various directions) are located throughout the platform and create a transparent ceiling over the promenade while shading the presence of the large building.
