ST. PETER'S - Vatican City
Project Overview
The project consisted of the integrated digital survey and creation of a Digital Twin of the seventeenth-century body of St. Peter’s Basilica, one of the most complex and symbolically significant architectural assets worldwide.
The main objectives were:
creation of a centralized digital repository of heterogeneous historical and survey data;
development of a high-resolution 3D model to support structural monitoring and long-term asset management.
The activities included large-scale data acquisition campaigns involving:
management of up to 25,000 high-resolution images,
Resolution: 3/6/12 mm at 10 m, variable depending on the environments being surveyed
3D point accuracy: 1.9 mm at 10 m / 2.9 mm at 20 m / 5.3 mm at 40 m
handling of approximately 3 TB of raw data,
integration of multi-source datasets into a unified digital environment.
The resulting Digital Twin, based on textured 3D meshes and high-density point clouds, enables:
advanced structural analysis and monitoring design,
digital support for maintenance and engineering interventions,
long-term data integration within a dynamic asset management system.
The model also provides a foundation for future applications in energy management, conservation and cultural valorization, supporting both technical stakeholders and institutional entities managing the Basilica.
