AS Asti was established by Ministerial Decree of April 15. 1959; the home was completed in 1964. Since then, in addition to some private archives and public bodies, it has collected what remained of State offices that are located in the current provincial constituency. In 1935 it was incorporated with the province of Asti in the territories, in particular those of Alessandria and Cuneo. The current territory therefore includes areas that over time were part of various constituencies (beyond those already remember, Acqui, Casale and especially); preunitaria documentation is fragmentary, and accordingly it is, to a large part, kept at the AS Torino, and in lesser part at AS Alexandria.
