The transformation of mining and industrial spaces into tourist spaces is part of the debate surrounding the profound changes in the contemporary economies of developed European countries. The loss of competitive power of their traditional companies, the obsolescence of many manufacturing facilities, and the take-off of other industrial economies in remote parts of the world have led to the closure of thousands of mines and factories, with the approval of environmental groups. In some privileged places, these ex-industrialized spaces have recovered environmentally, been allocated aid for socio-economic reconversion, and reoriented the old mines and factories (now converted into industrial heritage), towards cultural and tourist uses. The successful examples of Ironbridge, Zollverein or Wieliczka, have created the illusion to managers, owners, and local population of being able to turn almost any ruin of the industrial and mining past into a tourist attraction. Starting in the 1990s, many ex-industrial spaces, which were far from the main urban centres, opted for this tourist transformation as a lifeline to slow down the loss of population and economic activities. Sometime after these projects of industrial tourism, the result can be evaluated with objective data that question the sustainability of the model and the resilience of these places. This paper focuses on questioning the sustainability and resilience of the tourist transformation of two former mining areas located in Spain (Almadén and Sabero), far from the axes of economic development.
