The new architectural models were imitated within the historic centre with the contruction of numerous palazzi, giving rise to a unique system of residences for the nobility, which was made official in 1576 by a Decree of the Senate promulgating an official list of palazzi obliged to host state visits (list of the Public Lodgings or Rolli), according to their particular value.

The area included in the inscription therefore extends to a section of the historic centre which runs through Via Lomellini, Piazza Fossatello and Via San Luca and terminates at Piazza Banchi, the mercantile heart of the historic city: along this stretch are located some of the most significant examples of the Palazzi dei Rolli built in the Modern Period within the mediaeval fabric.
