| Abstract |
The idea of the digital twin (DT) originated in NASA’s Apollo Space Program during the 1970s, but it was formally defined by Michael Grieves in 2002 as the “virtual representation of what has been produced.” Initially, from 1970 to 2000, DTs were mainly applied in astronautics and aerospace. However, since 2001, their use has expanded into the industrial sector, with significant applications in the manufacturing, aerospace, and automotive industries. This cultural shift improved their application in creating, constructing, and overseeing virtual products grounded in real-world parameters, with an increased focus on informatics (since 2011), construction (since 2016), and heritage (since 2020) sectors. In these contexts, DTs replicate the physical behavior of heritage objects within virtual environments, facilitating multiphysics modeling and continuous model updates through automated data monitoring. In the realm of heritage and tourism in smart cities, DTs have found diverse applications, spanning pathology mapping, predictive maintenance, energy simulation, building management, and virtual and augmented reality. Their integration is intricately linked with concepts such as the Internet of Things and artificial intelligence (AI), particularly in devising devices for monitoring microclimatic conditions, airflow, air quality, noise, and lighting pollution to assist in the proactive preservation of artifacts, predicting deterioration patterns, and recommending optimal conservation measures. Also, Heritage Building Information Modeling can help with concept design, construction, scheduling, estimation, and prediction. Immersive technologies and AI-driven DTs can enhance visitor experiences through personalized interactive guides, immersive storytelling, and virtual reconstructions of historical sites. Integrating blockchain technology can secure provenance data, ensuring the authenticity of heritage items. This chapter will delve into the evolution and applications of DT, AI, and immersive technologies in the heritage and tourist sectors, with a focus on the integration with blockchain to promise innovative and sustainable approaches for engaging and safeguarding the cultural legacy. This concept gives rise to the “Heritage 4.0” framework, where industrial production, cyber-physical systems, and digital and computational technologies come together. © 2025 Elsevier Inc.
