The Triano Mountains stand as a symbol of the Basque Country’s mining heritage, mirroring the industrious efforts that have shaped the landscape since the mid-19th century. In the early 20th century, this corner of Meatzaldea (in Basque, "the mining area"), which includes the towns of Trapagaran, Ortuella and Abanto-Zierbena, rose to prominence as one of Europe’s most vital mining centres. Exploring these landscapes reveals a truly evocative space. Here, visitors can almost hear the echoes of the frenetic industrial activity, social life and passionate struggles of the early 20th century.
