Diagonal Mar Shopping is one of the biggest shopping centres in Barcelona and Catalonia. It is situated on the Poblenou waterfront in the borough of Sant Martí in the Diagonal Mar neighbourhood. Diagonal Mar is one of the Catalan capital’s newest neighbourhoods and is the result of the new urban plan designed for the 2004 Universal Forum of Cultures. It takes its name from its location at the end of the Avinguda Diagonal right by the Mediterranean. This new development has given the shopping centre a unique location. Diagonal Mar Shopping is next to the Forum, CCIB (Barcelona International Convention Centre) the Telefónica headquarters (Movistar), Districte 22@ and a number of renowned hotels including the Hotel Princess, Hotel Hilton, Hotel AC and Hotel Zero. Diagonal Mar opened on 20th November 2001 and has more than 200 shops (88,000 m²) set out on three floors. It also has an underground car park for 5,000 vehicles.
