La cittadella di Alessandria negli sviluppi di periodo napoleonico (1808-1860): la conoscenza come parametro di progetto

Following the essay entitled “La cittadella di Alessandria nel primo impianto bertoliano (1728-1761): la conoscenza come parametro di progetto” this contribution summarizes investigations carried out since 1991 on the Citadel of Alexandria, no longer referring to the original project by Ignazio Bertola (1728), but to the subsequent stages of completion of the outer wall and of the internal buildings, both in the Napoleonic period, and in the following phases, including the monitoring of the phenomena of instability and degradation, which in some cases occurred at the time. These specific surveys are part of the wider "development projects" planned for the fortress in the Alessandria defence area.
