moves during earthquakes showed a clear pattern of increased displacements at the top levels, which matches the tower's design and features like masonry columns and windows. The successful use of advanced SHM technology with cloud-based analytics in this complex historic building shows how these systems can help preserve heritage and reduce seismic risks. The QMEMS sensors work as well as high-quality force-balance accelerometers, proving they are good for monitoring structures and studying earthquakes. Overall, our project enhances the safeguarding of the Basilica and contributes to the broader field of structural monitoring of monumental buildings exposed to complex and evolving loading scenarios. 7. Acknowledgements The authors want to thank the Sacro Convento of Assisi (namely the Custodian Father Marco Giuseppe Moroni and the head restorer and Director of the technical office Prof. Sergio Fusetti) for granting access to the bell tower and the vaults of the Basilica and for providing the architectural drawings essential for this study. We also want to thank Wise Robotics for designing the monitoring system and for providing the data analytics platform and Seiko Epson Corporation for providing the M-A552 accelerometers. Appreciation is extended to INGV for integrating the OSU seismic station. References Cacciola, P., Caliò, I., Fiorini, N. et al.
