To endorse this hypothesis there are different elements: the presence of centurations and the discovery, in the Middle Ages, of a Roman marble slab, now kept in the Archaeological Museum of Milan.

The perspective axis at the entrance, although now partially interrupted visually by a green patch of trees and shrubs and the surrounding wall, has remained substantially intact over time.

The young woman, then nineteen years old (and thus a minor according to the law at that time), was placed under the guardianship of Giorgio Bergamasco, with Cesare Previti as pro-guardian.

On 26 July 1972 Bergamasco was appointed Minister for Relations with Parliament in the second Andreotti government;[15] meanwhile, Casati Stampa had already emancipated from guardianship upon turning twenty-one on 22 May 1972.

Subsequently, Anna Maria Casati Stampa, who had married Count Pierdonato Donà dalle Rose, moved with her husband to Brazil, and her Italian legal representative was her former pro-guardian Cesare Previti.

Pressed by financial needs and having inherited not only family assets but also significant tax arrears from her father, Anna Maria Casati Stampa di Soncino in Donà dalle Rose decided in 1973 to sell the villa and appointed her lawyer, Cesare Previti, as broker.

The villa was eventually sold in 1974—at a price much lower than its assessed value[16]—to Milanese entrepreneur and future Prime Minister Silvio Berlusconi, who lived there until his death in June 2023.
