University of Bradford Leads Digital Heritage with 3D Models to Preserve Historic Towns

Why Digital Twins Matter for Heritage Conservation

The rise of 3D scanning and immersive visualization has shifted the way we document, study, and protect heritage sites. For professionals in the UK who work with historic buildings, urban landscapes, or cultural assets, digital twins provide a precise record that can survive after the physical object has changed or deteriorated. The University of Bradford’s recent projects in Kilmallock and Derry demonstrate how these tools can be applied at scale, turning research into tangible assets for planners, educators, and visitors.

University of Bradford’s Pioneering Technology

Professor Andrew Wilson and his team employed a mix of vehicle-mounted laser scanners, drone‑based LiDAR, and handheld mobile mapping to capture every angle of the medieval walled towns. The data produced a high‑density 3D mesh that supports a variety of use cases:

• Interactive online tours for students and the public.
• Accurate baseline records for conservation and regeneration work.
• Data layers that can be imported into GIS or architectural software.
• Visual aids for tourism marketing campaigns.

These models are freely accessible through platforms like Sketchfab and enable users to navigate the streets of Derry or Kilmallock at any time, without travelling physically.

Linking Historical Storytelling With Modern Tools

The partnership between the University of Bradford, the University of Limerick, and Derry City and Strabane District Council illustrates an effective stakeholder model. By combining academic research, local governance, and community interest groups such as the Friends of the Derry Walls, the project gained both expertise and public trust. The initiative was funded through the Arts and Humanities Research Council’s Capabilities for Collections scheme, a model that other regional councils could emulate.

How the Data Supports Urban Regeneration

Local authorities can use the detailed datasets to:

1. Model the impact of proposed road closures or building modifications.
2. Identify structural vulnerabilities through 3D stress analysis.
3. Produce visual mock‑ups for grant applications and community consultations.

Because the models are built on open standards, they integrate seamlessly into planning software used by most UK councils.

Educational and Tourism Benefits

For educators, the interactive 3D experiences allow students to explore complex architectural concepts without leaving the classroom. Similarly, tourism operators can incorporate virtual tours into destination marketing, attracting visitors who might otherwise miss out due to accessibility or distance constraints.

Case Study: Virtual Bradford

The University of Bradford previously created a high‑resolution 3D digital twin of its own city centre, demonstrating the viability of the approach on a smaller scale. By linking that project with the wider international heritage collaborations, the university signals its commitment to leveraging immersive technology for cultural impact.

Practical Steps for Heritage Professionals

1. Assess Your Asset: Identify sites that would benefit from detailed documentation—this could be a centuries‑old manor, a historic street, or a vulnerable monument.

2. Choose Appropriate Scanning Technology: Vehicle‑mounted scanners work best for large open areas; drones are ideal for rooftops and hard‑to‑reach spots; handheld units can capture interior spaces.

3. Build an Interdisciplinary Team: Collaborate with architects, GIS specialists, and digital artists to ensure the data is usable across platforms.

4. Adopt Open File Formats: Store the raw and processed data in formats such as .las or .laz for point clouds, and .obj or .gltf for meshes, to guarantee long‑term accessibility.

5. Publish and Engage: Host the 3D model on a platform that allows embedding, and promote it through local heritage networks and tourism channels.

Maintaining and Updating Digital Twins

Historic sites evolve; new construction, restoration work, or natural erosion can alter the original fabric. Establish a maintenance schedule that includes:

• Annual scans for critical changes.
• Versioning of the models to track progress.
• Cloud-based storage to enable rapid collaboration and backup.

These practices help keep the digital twin an accurate reflection of reality, which is essential for both heritage interpretation and regulatory compliance.

Future Opportunities and Partnerships

With the University of Bradford extending its capability to the UK and Ireland, other regions can partner for joint projects—whether it’s mapping a coastal town’s heritage assets or creating a digital twin of a historic museum. Sharing tools and methodologies can reduce costs and accelerate deliverables for local councils.

Benefits for Academic Institutions

Academic programs in heritage conservation can integrate the modelling process into coursework, offering students hands‑on experience with real‑world data.

Benefits for Tourism Boards

Tourism boards can package virtual tours as part of destination apps, providing a novel channel for visitor engagement, especially in a post‑pandemic world where travel patterns are changing.

Key Takeaways for Professionals

1. Digital twins are an actionable tool for preserving heritage, informing conservation, and engaging communities.
2. The University of Bradford’s models demonstrate scalability, from a single town to international collaborations.
3. Open standards and interdisciplinary teams are essential for effective implementation.

By adopting these practices, heritage managers, urban planners, and educators can safeguard cultural assets now and for future generations.
