On the main floor of the Palazzo Ducale you will find the Archivio Storico del Comune. This impressive archive holds many documents detailing the republic’s administrative activities from the 15th Century up to the end of the 18th Century. It also holds the Administration Acts of the Government of the city and of the suburban councils from 1805. There are also private archives of the Brignole Sale family and the De Ferrari family, and the historical archives of the civil state (19th Century).
