The paper deals with the documentation project of the Rocca della Verruca, a medieval fortress built on top of one of the peaks of the Pisan Mountains to control the valley of the Arno river; the fortress was fortified in modern times by the Florentines and was visited by important architects such as Giuliano da Sangallo and Leonardo da Vinci. The path of knowledge undertaken in the documentation of the structures, which are now in a state of ruin, are aimed at analyzing the superficial and structural conservative state of the fortress. The survey operations were carried out using the most recent digital instruments: laser scanner, aerial photogrammetry and ground photogrammetry. The resulting three-dimensional model, highly reliable, was useful for carrying out analyzes on the structure, from morphological to diagnostic and structural ones. A careful mapping of the cracking framework was performed and through the analysis of the real based models coming from the relief of the wall deformations; the cognitive overview has made it possible to clarify the state of structural conservation of the building.
