Borromini and by Cortona The plan has three courtyards. The rooms on the piano nobile (the first floor) have frescoes and friezes by artists such as Giacinto Gimignani, Gaspard Dughet, Andrea Camassei, Giacinto Brandi, Francesco Allegrini, and Pier Francesco Mola. Carlo Rainaldi, the son of Girolamo, completed the building around 1650. The new palazzo became the home of Innocent's widowed and unpopular sister-in-law Olimpia Maidalchini, who was his confidante and advisor and, more scurrilously, reputed to be his mistress. She was the mother of Camillo Pamphilj, the one time cardinal, who through his marriage came into the possession of the Palazzo Aldobrandini, now known as the Palazzo Doria Pamphilj. Confusingly, until the unification of the Doria and Pamphilj surnames both palazzi were known as Palazzo Pamphilj, or in the case of today's Doria Pamphilj sometimes "Palazzo Pamfilio". Both spellings Pamphilj and Pamphili are in common Italian usage, even though the family prefers Pamphilj. References Bibliography Leonie Stephanie.
