Comprehensive Technical Inspection of a Medieval Bridge (Ponte de Vilanova, in Allariz) Using Microtechnological Tools

Year: 2024
Type: article
Abstract: Ponte de Vilanova, a masonry bridge, was built in Allariz, Galicia, in the 13th-14th centuries. It is still standing. The structure, generally well-preserved, shows minor deformations and wear signs caused by environmental factors. To conduct a comprehensive assessment without impacting the bridge’s integrity, drones with thermal and underwater imaging technology were employed. Aerial inspections revealed vegetation growth and minor efflorescence (salt deposits) in some areas, while aerial thermography detected temperature variations along the stone joints, indicating moisture presence. The granite blocks comprising the bridge showed consistent quality and preservation. The underwater inspection confirmed that the bridge’s piers are well-set on the riverbed, with no major damage observed, ruling out immediate repair needs. This approach allowed a thorough evaluation of submerged parts without requiring divers, enhancing safety and reducing costs.
