This project contributes to climate change adaptation of the heritage city of Salamanca, focusing on introducing nature-based solutions. To achieve this, different actions have been implemented, such as the development of the city's adaptation action plan, including decision-making tools and a roadmap for adaptation, the application of machine learning to identify climatic zones, and the development of a green corridor through the city. This innovative project presents “the green heritage” as a path for other cities to explore and further develop a network of Heritage Adaptation Cities.
