Its main urban core is surrounded by two small mountain ranges with an average elevation of 400 metres (1,300 ft).

After its foundation in the early 14th century by Diego López V de Haro, head of the powerful Haro family, Bilbao was a commercial hub of the Basque Country that enjoyed significant importance in Green Spain. This was due to its port activity based on the export of iron extracted from the Biscayan quarries. Throughout the nineteenth century and the beginning of the twentieth, Bilbao experienced heavy industrialisation, making it the centre of the second -most industrialised region of Spain, behind Barcelona.
