This study examines visitors' perceptions of industrial mining heritage in Spain, a sector of
significant cultural and economic value that has led to the establishment of museums and mining
parks, which have been transformed into tourism products. Using text mining and natural language
processing techniques, Tripadvisor’s online reviews of nine industrial mining heritage resources
distributed across different autonomous communities in Spain were analysed. The primary objective
was to investigate how visitors describe and evaluate their experiences at these sites. The results
indicated a generally positive perception, with visitors frequently citing terms such as "interesting,"
"recommendable," and "spectacular." However, critical points were also identified, particularly in
relation to the duration and physical demands of the visits. This study highlights the educational
and aesthetic importance of these sites, recognising their value in teaching the history of industrial
mining and in offering cultural tourism.
