In 1974, Ames's heirs sold the villa to businessman and explorer Count Guido Monzino (leader of the first Italian expedition to climb Mount Everest). While Monzino left the exterior essentially unchanged he had the interior of the villa completely re-decorated, installing artifacts acquired on his expeditions as well as important pieces of English Georgian and French antique furniture from the 18th and 19th centuries, Beauvais tapestries, French boiseries and Oriental carpets. After the assassination of Aldo Moro in 1978 by the Red Brigade, Monzino became worried about his safety, and added a system of hidden passages, linking parts of the property.
