What Spain Teaches Us About Climate Change and Cultural Heritage

Climate

From floods to wildfires, Spain’s World Cultural Heritage Sites are in danger. Discover how climate change threatens cultural memory—and what Spain is doing to defend it before it’s too late.

Spain is home to 50 World Cultural Heritage Sites (WCHS) that represent a significant incentive for tourism, a fundamental sector of the Spanish economy and its main source of income. Spain is, in fact, the second most popular tourist destination in the world, with sites like the Alhambra de Granada and Gaudí’s Sagrada Familia leading travel bucket lists of many visitors. The current climate crisis, however, threatens to severely damage our buildings and relics, and by consequence, the historical memory interwoven with them.

For instance, extreme precipitation in coastal areas can cause soil saturation and the overload of ditches and downspouts, exacerbating the risks of flooding in WCHS and of material corrosion due to the infiltration of moisture and water. Santiago de Compostela is at risk of hydraulic erosion due to the increasing amount and intensity of rainfall, whereas in 2024, the DANA storm devastated the Valencian Community, sweeping away homes, bridges, and buildings of cultural and historical relevance such as the Iglesia de la Mare de Déu de la Salut—not to mention the more than two hundred people who died.

Intense rainfall and flooding in regions like Navarra have led to the development of local flood risk management and emergency plans supported by real-time river monitoring systems and early warning alerts, which are coordinated through regional civil protection services. At the national level, Spain’s National Climate Change Adaptation Plan (PNACC) explicitly frames cultural heritage as a priority sector, aiming to identify the Spanish cultural sites most vulnerable to climate change and to implement adaptation strategies to increase their resilience.

The overall trend in Spain, however, is towards warmer and drier conditions. Under a 3°C global warming scenario, it’s estimated that the east and south of Spain will transition from Mediterranean to desert climate, characterized by aridity and hot temperatures. Most of the Spanish World Heritage Sites, including the spectacular Sitio Arqueológico de Atapuerca and the Ciudad Califal de Medina Azahara, are located in green areas vulnerable to wildfires, the majority of which already have fire risks exceeding 60%. The intensification of the country’s characteristic dryness and heat due to climate change will only increase these percentages.

Last summer, a fire affected the Mezquita-Catedral de Córdoba, a World Heritage Site since 1984. Following the accident, the Ministry of Culture immediately activated the National Plan for Risk and Emergency Management in Cultural Heritage to coordinate technical support with local authorities in assessing the damage and initiating restoration. Beyond reactive measures, Spanish authorities have increasingly emphasised the importance of prevention and risk management. At specific sites, simulated emergency exercises have been conducted; for instance, the Conjunto Arqueológico Dólmenes de Antequera hosted Spain’s first heritage evacuation drills. Spain is also implementing global tools such as the UNESCO Fire Risk Management Guide, which offers a structured framework for assessing hazards and strengthening preparedness under intensifying climate stress.

Spain’s works of art—from frescos and sculptures to architectural complexes and hand-painted ceramics—do not only reflect the artists’ individual creativity, but also embody the spirit of the nation itself. They constitute the direct materialization of the Spanish community’s moral and aesthetic values, promoting a sense of belonging and identity among its members while contributing to a shared feeling of humanity that transcends national borders. As climate change accelerates, Spain’s experience teaches us that cultural heritage cannot be preserved apart from the environment and that our cultural memory must be actively defended through policy and planning. The challenge, however, is universal, and converges in a single imperative: to adapt now in order to safeguard the irreplaceable cultural legacy that connects past, present, and future generations.
