This paper deals with the analysis of some examples of large wooden trusses in important churches of Bologna carried out through a survey campaign conducted with a laser scanner. This study helped to develop a wider methodology for instrumental survey, aiming to derive a series of significant information: average deviations of the structures compared to theoretical models, deformations of the elements through time, instability, material state of conservation, structural behaviour both locally and globally. All results highlighted the knowledge that the structural design of these wooden roofing is influenced by the original structural characteristics, the understanding of which is functional on any restoration intervention.
