The Rolli di Genova - or, more precisely, Rolli degli alloggiamenti pubblici di Genova - formed an official list at the time of the Republic of Genoa, of public lodging palaces and mansions of eminent Genoese families, which aspired to host - from a public lottery - the persons in transit for visits of state.In later times the same homes have hosted the distinguished visitors which included the Ligurian capital in their Grand Tour cultural and / or tourist itinerary.
