The rehabilitation of mining environments poses significant challenges due to the contamination risks associated with hazardous materials, such as arsenic and other chemical products. This research study presents the development of a Digital Twin for the Lavrion Technological and Cultural Park (LTCP), a former mining and metalworking site that is currently undergoing environmental restoration. The Digital Twin integrates advanced technologies, including real-time sensor monitoring, geophysical methods, and 3D modeling, to provide a comprehensive tool for assessing and managing the environmental conditions of the site. Key elements of the project include the monitoring of hazardous-waste storage, the evaluation of contaminated soils, and the assessment of the Park’s infrastructure, which includes both deteriorating buildings and successfully restored structures. Real-time sensor data are collected to track critical parameters such as conductivity, temperature, salinity, and levels of pollutants, enabling proactive environmental management and mitigation of potential risks. The integration of these technologies enables continuous monitoring, historical data analysis, and improved decision making in the ongoing efforts to preserve the site’s ecological integrity. This study demonstrates the potential of using Digital Twins as an innovative solution for the sustainable management and valorization of mining heritage sites, offering insights into both technological applications and environmental conservation practices.

The PATCULT 3D project was developed during the 2024–2025 academic year as part of the Degree in Geoinformation and Geomatics at the University of Salamanca (Spain) as a service-learning initiative designed to integrate technical training with social commitment. The main objective was to provide students with practical experience in photogrammetry, 3D laser scanning, and additive manufacturing applied to the documentation and reproduction of cultural heritage. A particular feature of the project was its collaboration with the Spanish National Organization of the Blind (ONCE), placing accessibility for people with visual impairments as a central methodological tenet. Students developed tactile replicas of heritage assets from the province of Ávila, applying universal design principles and implementing Braille-based information systems to ensure fully inclusive modes of cultural engagement. In addition to the digital preservation of heritage, the activity reinforced students’ technical skills (covering data acquisition, 3D modeling, mesh refinement, and digital fabrication workflows) while fostering transversal competences such as teamwork, communication, critical reflection, and social awareness. The evaluation instruments demonstrated high levels of motivation and satisfaction, as well as a growing sensitivity to the social responsibilities of geomatics. The project is explicitly aligned with Sustainable Development Goals 4, 9, 10, and 11, thereby contributing to quality education, technological innovation, the reduction in structural inequalities, and the fostering of inclusive and sustainable communities. Overall, the experience illustrates how the integration of digital technologies with service-learning can strengthen academic training and, at the same time, generate measurable social value by making cultural heritage more accessible.
