Man constructs and reports history and, therefore, the official record can be conventional and synchronous to parallel re-elaborations: this dichotomy coupled mostly with grand historical events also permeates the historiography on the epic of Napoleon Bonaparte. The Mombello Convention signed on 6th June 1797 in Limbiate between the Generalissimo and the Republic of Genoa sanctioned the birth of the Ligurian Republic (1797 – 1805) and the fall of the aristocratic oligarchy. This Agreement, ratified in Genoa on June 9th, established the government of twelve members and the president appointed by the bicameral parliament (300 and 150 members) and regulated the territorial division into units of municipalities and districts. The provisional government of twenty-two members led by Marquis Giacomo Maria Brignole coordinated the work to build the republican structure. The disagreement between Lombardy and Piedmont revolved around the location defined for the signing of the agreement: the document, drafted by Napoleon together with the minister plenipotentiary Guillaume-Charles Faipoult de Maisoncelles, was signed at Palazzo Tornielli in Mombello Monferrato. This thesis on the location for the signature on the agreement is displayed on the website http://www.comune.mombellomonferrato.al.it/Home/Guida-al-paese?IDPagina=31413 is also defended by the ‘Palazzo Tornielli’ cultural association based in the noble residence of the same name, formerly the seat of Palazzo Pretorio (1300) and residence of the Aleramo dynasty. The renovation commissioned by the current Morone owners, Federica (daughter) and Carlo (father), on the structure dating back to the 15th century enhances the refined charm of the airy frescoed rooms adorned with antique fireplaces. The elegant loggia is open to the hilly landscape of Val Cerrina.
