Cities

The Iberian city network is dominated by three international metropolises (Barcelona, Lisbon, and Madrid) and four regional metropolises (Bilbao, Porto, Seville, and Valencia). The relatively weak integration of the network favours a competitive approach vis-à-vis the inter-relation between the different centres. Among these metropolises, Madrid stands out within the global urban hierarchy in terms of its status as a major service centre and enjoys the greatest degree of connectivity.
