As with every building involving architectural orders, corner solutions are closely related, in Palladio’s work, to the rapport between the orders and the overall building and, in the case of orders engaged to the wall, to the intense dialectic between walls and columns. Through the analysis conducted on a series of projects and realisations, containing significant passages of Palladio’s research around these themes, the study returns a path that winds its way from one project to the next with continuous reworkings and completely personal inventions. Possible links and derivations from ancient and modern models, mainly from the Roman ambit, are also highlighted and discussed, with attention to the ways in which the different sources are used in design, up to the achievement of innovative formal outcomes.
