Uztaro

xix. mendearen erdialdean, Aizarna herri txikiak bere industria-iraultza propioa bizi izan zuen, bertako mendietan ugariak ziren meategiak ustiatzen hastean; jarduera hori Urola bailaran ezartzen hasi berriak ziren zementu naturalaren fabriken garapenari oso lotuta egon zen. Ia mende batez herrira aberastasuna ekarri ondoren, Gerra Zibilaren osteak meategien ekoizpenaren beherakada eragin zuen meategiak ixteraino.

In the middle xixth century, the small town of Aizarna went through its own industrial revolution, when the exploitation of the coalmines, which abounded in its mountains began. This activity was closely bound to the development of natural concrete factories which were being set up in the Urola Valley. After nearly a century bringing prosperity to the town, the postwar years of the Spanish Civil War led to the downturn of the production and the shutdown of these mines.
