 Throughout Italy inspiring architects received training on-the-job.In most parts of Italy, local architects satisfied building needs, but in Rome architects were specifically commissioned either by the Papal state or family dynasties to work on their projects.Families associated with the papacy, including the Barberini, Borghese, Chigi and Pamphili, were extremely well off and, in turn, some of the richest and grandest villas were constructed for them.
