This work was created by or on behalf of either the government, the former national Fascist Party, an academy, or a non-profit organisation of Italy. It was published prior to 1976, and has no known US copyright registration associated with it. It is now in the public domain in Italy and the United States and possibly elsewhere because its copyright term has expired. According to Law for the Protection of Copyright and Neighbouring Rights n.633, 22 April 1941, revised by the law of 6 February 2016, copyright in works created and published under the name and at the expense of national, provincial and communal governments shall belong to the relevant administration; the same right shall also belong to private legal entities of a non-profit-making character, as well as to the academies and other public cultural organisations (Art. 11). The duration of the rights belonging to the government, the former national Fascist Party, academies and non-profit or public cultural organisations shall be twenty years from first publication, whatever the form in which publication was affected (Art. 29).

United States copyright law does not protect architectural works before 1 December 1990. In 1990, the Architectural Works Copyright Protection Act amended subsection 102(a) of the US copyright law by adding paragraph (8), "architectural works." A building that was substantially constructed or for which the plans were otherwise published before 1 December 1990, is in the public domain in the United States.
