Digital survey and 3D geometric interpretation of complex vaulted systems. Palazzo Valperga Galleani di Barbaresco in Turin

The present contribution proposes the study of the 'a fascioni' vaults, which derive from Guarini's experience, that characterized, between the seventeenth and eighteenth century, part of the baroque architectural production in Piedmont. Such unitary vaults are characterized by the subdivision, through twisted arches, of the intrados into regular fields, covered by secondary vaults. The case study presented, Palazzo Valperga Galleani di Barbaresco in Turin, aims to deepen, through 3D representation digital tools, the links between the realizations, the references to treatises and manuals and the geometric matrices behind the articulated spatial configurations.
