Continuing the commercial traditions of its golden age as a medieval port, the Catalan capital is a popular business location for the international market, attracting more foreign investment than any other Spanish city. The impressive Fira de Barcelona congress centre in Plaça d’Espanya hosts five of the eleven top trade events in Europe, including the 3GSM mobile phone convention and Bread and Butter, one of the world’s top fashion fairs. The centre’s facilities are being extended in the Gran Via M2 development.
