Table 1: Cont. digital leaflets in or 3D models from photographs; and (xiv) access to multimedia tools (videos, audios, augmented reality, etc.). The heritage site with the highest web popularity index (WPI) is the Almaden mining area (now the Almaden Mining Park) (Figure 2). The next buildings or areas, with a slightly lower WPI, are as follows: Vapor Aymerich, Amat y Jover textile factory (now the Catalonia National Museum of Science and Technology, MNACTEC), water lift (now the AGBAR Water Museum), Royal Glass Factory (now the Glass Technology Museum), Real Casa de la Monica, Anana Salt Mines and San Blas Ironworks (now the Castile-Leon Iron & Steel and Mining Museum). Almost all the specified variables are present in this first level of selected buildings and areas, which can be regarded as spaces with a highly technological web presence.
