The Archive of the Civic Historical Collections, today preserved in the headquarters in via Borgonuovo 23, originates fromArchive of the Risorgimento which was organically established when the Museum of the Risorgimento in Milan was set up in the Rocchetta rooms of the Sforzesco Castle at the beginning of the twentieth century.
The War Archive was added to the original collection, which includes extremely important funds, including the Carlo Cattaneo, Cesare Correnti and Agostino Bertani archives, in 1925.
During the bombings of 1943 the collections suffered serious damage and some of the documents were lost. In the last few years the Archive has expanded considerably thanks to numerous purchases and donations.
