Abstract

Digital twin technology, commonly defined as a virtual representation of a physical object, environment, or system, has moved beyond its industrial origins and has increasingly entered tourism research and practice. In tourism, digital twins are being used to represent cultural heritage sites, museums, monuments, urban destinations, and related visitor environments in digital form. This article presents a systematic review and bibliometric synthesis of digital twin applications in tourism, with particular attention to cultural heritage contexts. Drawing on thirty-four peer-reviewed studies published between 2021 and early 2025, the review examines publication trends, major application domains, spatial scales, data architectures, and visualization approaches. The analysis shows that the literature is growing, but it remains conceptually and technically uneven. Most existing applications are concentrated in cultural heritage tourism and operate mainly at the site level, such as museums, archaeological areas, and monuments. In addition, a large share of current systems still rely on one-way data flows in which the physical environment updates the digital model without enabling real-time reciprocal interaction. This limits the adaptive and operational potential often associated with digital twin systems. The review proposes a structured taxonomy for classifying digital twin applications in tourism and identifies several priorities for future research, including real-time synchronization, integrated data ecosystems, user-centered design, governance models, and scalable implementation frameworks. The article contributes to the growing digital tourism literature by clarifying the current state of the field, identifying its conceptual and technical limitations, and outlining a more coherent agenda for future empirical and applied work.

1. Introduction

Digital transformation has become one of the defining developments in contemporary tourism. As destinations, cultural institutions, and tourism operators seek more intelligent ways to manage resources, engage visitors, and preserve assets, attention has increasingly turned to digital twin technology. A digital twin is generally understood as a dynamic digital representation of a real-world entity or environment. Unlike static digital models, digital twins are expected to reflect changing real-world conditions and, in more advanced cases, support interaction between physical and virtual systems.

Originally developed in manufacturing, engineering, and industrial operations, the digital twin concept has progressively expanded into domains such as healthcare, urban planning, logistics, and environmental monitoring. Tourism has emerged as a newer but increasingly relevant field of application. In this context, digital twins are being used not only to replicate physical spaces but also to support preservation, interpretation, planning, accessibility, and visitor management. Their relevance is especially visible in cultural heritage tourism, where the need to protect fragile physical assets often intersects with the demand for wider public access and richer interpretive experiences.

The rise of digital twins in tourism can be linked to several broader developments. First, tourism systems are becoming more data-intensive through the growth of sensors, geographic information systems, digital platforms, and immersive technologies. Second, heritage sites and destinations increasingly require planning tools that can support sustainability, crowd regulation, risk reduction, and informed decision-making. Third, visitors now expect more personalized, interactive, and digitally mediated experiences before, during, and after travel. Within this environment, digital twins offer a promising framework for connecting physical spaces, digital models, and human interaction.

At the same time, the expansion of digital twin discourse in tourism has outpaced conceptual clarity and practical maturity. The term is sometimes used broadly to describe digital replicas, 3D reconstructions, virtual tours, or spatial dashboards, even when these systems do not include the real-time synchronization or feedback mechanisms that are central to stronger definitions of digital twins. As a result, there is a need to review the emerging literature carefully and distinguish between aspirational claims and actual system capabilities.

This article addresses that need through a systematic literature review and bibliometric synthesis of digital twin applications in tourism. It focuses especially on cultural heritage tourism while also considering urban and destination-level uses. The article has three main objectives. First, it maps the current scope and direction of research on digital twins in tourism. Second, it identifies the main technical and conceptual patterns that define the field, including dominant use cases, data flow structures, and visualization approaches. Third, it proposes a research agenda that can support more robust, adaptive, and user-oriented development in the years ahead.

2. Methodology

This article adopts a systematic literature review approach combined with bibliometric synthesis in order to provide a structured overview of digital twin research in tourism. The purpose of this method is to reduce fragmentation in the literature and to identify recurring themes, limitations, and emerging directions in a transparent and replicable manner.

The review covered peer-reviewed studies published between 2021 and early 2025. This period captures the early growth phase of digital twin research in tourism and reflects the point at which the topic began to gain more visible academic attention. Major academic databases, including Scopus and Web of Science, were used as primary sources, alongside relevant conference proceedings where appropriate. Search terms combined the concept of the digital twin with tourism-related terms such as tourism, cultural heritage, destination, museum, smart tourism, and virtual tourism.

The screening process applied inclusion criteria designed to retain studies that were directly relevant to digital twin applications in tourism. To be included, studies needed to discuss tourism-related environments, destination systems, cultural heritage sites, or visitor-facing applications and to engage substantially with digital twin concepts rather than only peripheral digital technologies. After filtering for relevance and peer-review status, thirty-four studies were retained for final analysis.

A structured extraction process was used to classify the selected studies across several dimensions. These included the application domain, the spatial scale of implementation, the type of data used, the nature of the relationship between physical and digital systems, and the visualization or interface format. The review also examined thematic patterns through bibliometric mapping, including publication trends, keyword clustering, and conceptual concentration areas.

This methodological design offers two advantages. First, it allows the field to be assessed in a systematic and comparable way. Second, it enables the review to move beyond simple description and toward analytical interpretation by identifying where digital twin research in tourism is advancing and where it remains limited.

3. Evolution of Digital Twin Research in Tourism

The literature indicates that digital twin research in tourism has emerged relatively recently but is developing with growing momentum. Initial publications began to appear around 2021, reflecting wider interest in smart destinations, digital heritage preservation, and immersive tourism technologies. By early 2025, the topic had gained greater visibility, although the field still remains modest in size compared with more established areas of digital twin research such as manufacturing or urban infrastructure.

This timing is significant. Tourism entered the digital twin conversation at a moment when the sector was already rethinking resilience, sustainability, and digital engagement. The growing availability of 3D modeling, sensor systems, VR environments, GIS layers, and data dashboards created technical conditions that made tourism applications more feasible. At the same time, institutions responsible for heritage management and destination planning increasingly recognized the value of digital representation for conservation, communication, and strategic decision-making.

However, the field remains uneven in both terminology and maturity. In some cases, digital twin is used precisely to refer to dynamic systems connected to their physical counterparts. In other cases, the term is applied more loosely to advanced digital replicas, heritage reconstructions, or virtual environments that do not necessarily involve real-time updating or continuous data exchange. This conceptual breadth has helped expand the field, but it has also created ambiguity. A central task for the literature, therefore, is not only to document applications but also to clarify what counts as a digital twin in tourism and what remains a related but distinct form of digital representation.

4. Main Application Domains

4.1 Cultural Heritage Tourism

Cultural heritage tourism is the dominant application area in the current literature. More than two-thirds of the reviewed studies focus on heritage environments such as museums, monuments, archaeological sites, historic buildings, and culturally significant public spaces. This concentration is not surprising. Heritage contexts are particularly suitable for digital twin development because they involve physical assets that require documentation, preservation, interpretation, and controlled access.

In these settings, digital twins can serve several roles simultaneously. They can support conservation by creating detailed digital records of fragile or threatened structures. They can facilitate risk assessment by enabling simulation and condition monitoring. They can also enhance public engagement by providing virtual access to sites that are remote, damaged, restricted, or difficult to interpret without digital support.

The strong presence of cultural heritage in the literature also reflects a wider shift in heritage management toward digital mediation. Yet the review suggests that many heritage-focused digital twins still operate more as sophisticated representation tools than as fully interactive management systems. While they often provide high visual fidelity, many remain weak in terms of integrated data architecture, user analytics, or bidirectional control.

4.2 Destination and Urban Tourism

A smaller but growing group of studies addresses destination-level or urban tourism applications. These works move beyond individual sites and consider broader environments such as districts, city centers, or integrated tourism systems. In such cases, digital twins are linked to smart city infrastructures, mobility systems, environmental monitoring, and urban planning processes.

Destination-level twins are particularly important because tourism management increasingly requires coordinated oversight of flows, capacities, environmental pressures, and public services. A digital twin at this scale could potentially support crowd regulation, transport planning, event coordination, sustainability management, and destination scenario analysis. However, the review shows that these applications remain less common than site-based models, partly because they require more complex institutional coordination, larger data infrastructures, and stronger interoperability across systems.

5. Spatial Scale of Implementation

The reviewed studies reveal a clear preference for site-level implementation. Most digital twins in tourism are designed around specific places such as a museum, monument, building, or heritage complex. Site-level projects are easier to define, manage, and visualize. They also align well with current capacities in 3D scanning, VR design, and heritage documentation.

By contrast, destination-level twins are still relatively rare. These larger systems require the integration of multiple sites, infrastructures, stakeholders, and data streams. They must also respond to more complex governance questions concerning ownership, data stewardship, operational authority, and cross-sector collaboration. As a result, the literature shows that tourism digital twins remain concentrated in localized demonstration settings rather than fully developed destination ecosystems.

This imbalance has implications for future research. Site-level twins are valuable for proof of concept and targeted heritage work, but tourism as a system often operates across wider spatial and organizational scales. If digital twin research is to contribute more strongly to destination governance, future studies will need to address multi-site integration, urban interoperability, and regional planning capabilities.

6. Data Flow and System Dynamics

One of the most important findings of the review concerns the difference between unilateral and bilateral data architectures. Most tourism digital twins currently function through one-way or largely passive data flows. In these systems, data from the physical environment may update the digital model, but the twin does not meaningfully influence the physical environment in return. This structure can still be useful for visualization, documentation, and monitoring, but it falls short of the more advanced digital twin ideal based on dynamic interaction and reciprocal synchronization.

Only a small minority of studies describe systems with more bilateral or real-time characteristics. These more advanced models allow ongoing communication between physical and digital layers, enabling adaptive management, simulation feedback, or operational intervention. In tourism, such capabilities could support live crowd management, environmental condition control, predictive maintenance, personalized navigation, or interactive learning systems.

The relative absence of bilateral synchronization suggests that many tourism applications remain in an early developmental stage. This does not reduce their practical value, but it does indicate that the field has not yet realized the full analytical and operational potential often associated with digital twins. A key challenge for future research is therefore to move from representational systems toward adaptive systems.

7. Visualization, Interfaces, and User Interaction

The literature shows a strong emphasis on visualization. Common outputs include 3D reconstructions, GIS-based spatial layers, virtual tours, dashboards, and immersive environments built through VR or related technologies. These tools are especially useful in tourism because they make complex spaces legible to a wide range of users, including planners, visitors, educators, and conservation professionals.

However, the review also indicates that visualization quality does not always translate into meaningful user interaction. Many systems present visually impressive models but offer limited adaptability, personalization, or interpretive depth. In other words, the digital twin is often technically visible but not fully experientially or operationally active.

This finding matters because tourism is fundamentally a human-centered field. Technologies in tourism are not judged only by technical sophistication but also by how they shape understanding, movement, accessibility, decision-making, and experience. Future research should therefore examine not only what digital twins can display but also how different users engage with them and what outcomes they produce.

8. Benefits and Strategic Potential

Despite their current limitations, digital twins offer significant promise for tourism.

First, they can strengthen heritage preservation. High-quality digital replicas support documentation, restoration planning, risk assessment, and continuity of access in cases where the physical site is vulnerable or partially inaccessible. This is particularly relevant in heritage tourism, where preservation and public use must be balanced carefully.

Second, they can improve destination management. When connected to environmental, mobility, or visitor data, digital twins can support planning decisions, crowd distribution, resource allocation, and sustainability strategies. They may also enable scenario testing before physical interventions are made.

Third, they can enhance visitor experience and accessibility. Virtual previews, educational overlays, immersive interpretation, and remote access can expand participation and create more inclusive tourism environments. For visitors with mobility barriers, time limitations, or geographic constraints, digital twins may offer new forms of engagement that complement rather than replace physical travel.

Fourth, they can contribute to knowledge integration. Tourism often involves fragmented data across cultural institutions, municipal systems, transport services, and digital platforms. Digital twins offer a possible framework for bringing some of these layers together in a more coherent way.

The literature therefore suggests that digital twins should not be understood only as visualization tools. Their broader importance lies in their potential to connect preservation, management, and experience within a shared digital environment.

9. Key Challenges and Limitations

The review identifies several persistent challenges.

A first challenge is technical complexity. Building and maintaining a reliable digital twin requires detailed data capture, modeling capacity, infrastructure, and ongoing updating mechanisms. This can be costly and technically demanding, especially for smaller heritage institutions or destinations with limited resources.

A second challenge is data integration. Many current systems rely on isolated datasets rather than unified platforms. Sensor feeds, GIS layers, archival records, visitor behavior data, and platform analytics are often managed separately. Without integration, the digital twin remains partial and loses much of its potential analytical value.

A third challenge is limited real-time responsiveness. As noted earlier, many systems remain static or only periodically updated. This restricts their usefulness in live management situations and weakens the distinction between a digital twin and a conventional digital model.

A fourth challenge concerns conceptual overextension. The term digital twin is sometimes applied too broadly, creating confusion in both scholarship and practice. Not every 3D model or virtual reconstruction qualifies as a digital twin in a strong sense. Greater conceptual precision is needed if the field is to develop cumulative knowledge.

A fifth challenge involves governance and ethics. As digital twins become more data-intensive, questions emerge concerning privacy, ownership, representation, and long-term stewardship. These issues are especially important in tourism, where public spaces, cultural heritage, and human behavior intersect.

10. A Conceptual Taxonomy of Digital Twins in Tourism

To support clearer classification and future comparison, this review proposes a conceptual taxonomy based on five major dimensions.

Application domain: cultural heritage tourism; urban tourism; destination management.

Spatial scale: site-level; multi-site; destination-level.

Data relationship: unilateral; partially interactive; bilateral real-time synchronization.

Visualization mode: static 3D models; GIS-linked interfaces; dashboards; immersive VR or AR environments.

Primary purpose: preservation; interpretation; visitor engagement; planning; operational management.

This taxonomy is useful for both researchers and practitioners. For researchers, it provides a framework for comparing studies and identifying underdeveloped areas. For practitioners, it helps clarify the difference between digital presentation tools and more advanced operational twins. Most current tourism applications occupy the categories of cultural heritage, site-level scale, unilateral data flow, and visualization-oriented purpose. The movement toward destination-level, bilateral, and management-oriented twins remains limited but strategically important.

11. Future Research Directions

Several priorities emerge from the review.

The first is the development of integrated real-time ecosystems. Future digital twins in tourism should connect multiple data sources, including IoT devices, GIS layers, environmental monitoring, and possibly visitor-generated data where ethically appropriate. Such integration would allow the twin to function not only as a representation platform but also as an adaptive decision-support environment.

The second is stronger attention to user-centered design. Future studies should examine how digital twins affect visitor learning, satisfaction, interpretation, accessibility, and behavioral outcomes. This is especially important because technological success in tourism depends on human usability and relevance, not only technical performance.

The third is the need for practitioner-oriented frameworks. Many current studies demonstrate technical possibilities but provide limited guidance for destination managers, museum professionals, and heritage institutions regarding implementation, governance, or maintenance. Research should therefore produce more operational models that can be adapted in real settings.

The fourth is greater focus on ethics and governance. Issues such as privacy, digital ownership, cultural sensitivity, data stewardship, and environmental sustainability should be integrated into digital twin design from the beginning rather than treated as secondary concerns.

The fifth is the need for scalability and inclusion. Tourism destinations vary greatly in technological capacity. If digital twin systems are to support wider sectoral transformation, research should explore modular, open, and affordable approaches that can serve destinations with different levels of funding and infrastructure.

Finally, future work would benefit from empirical validation. Much of the current literature is conceptual, exploratory, or prototype-based. More applied research is needed to test performance, organizational value, user response, and long-term feasibility in actual tourism settings.

12. Conclusion

Digital twin technology represents an important and still developing frontier in tourism research. The literature reviewed in this article shows that the field has made visible progress, especially in cultural heritage contexts where digital twins support preservation, representation, and visitor engagement. At the same time, the review also shows that the current state of the field remains uneven. Most systems are concentrated at the site level, prioritize visualization over interaction, and rely on one-way data flows rather than real-time reciprocal synchronization.

These findings suggest that digital twins in tourism are promising but not yet fully mature. Their value is clear, but their strongest potential will be realized only when they evolve from static or semi-dynamic replicas into integrated, adaptive, and user-aware systems. This transition requires more than technical refinement. It also requires conceptual clarity, interdisciplinary collaboration, ethical awareness, and practical implementation models that fit the realities of tourism institutions and destinations.

By synthesizing the emerging literature and proposing a structured taxonomy, this article offers a clearer understanding of where the field currently stands and where it should move next. The future of digital twins in tourism will likely depend on the extent to which researchers and practitioners can bridge preservation goals, management needs, and visitor-centered design within coherent digital ecosystems. Under these conditions, digital twins may become not only a technological innovation but also a meaningful tool for more sustainable, accessible, and informed tourism development.
