Villa Giustiniani Odescalchi, Villa and museum in Bassano Romano, Italy.

Villa Giustiniani Odescalchi in Bassano Romano has its main entrance on the piazza facing the parish church, a massive wooden door flanked by four peperino busts supporting Roman marble heads from the 2nd century AD. The inner courtyard walls were frescoed by Antonio Tempesta with triumphal scenes, and the piano nobile is reached through a loggia painted with grotesques around 1570–1580. Its rooms hold frescoes including the Giustiniani coat of arms, the fable of Cupid and Psyche, the four seasons, Mount Parnassus, and the ports of Genoa and Chios.

The Anguillara family first owned the palace, which was altered in the 16th century. Its major works came in the 17th century under Marquis Vincenzo Giustiniani, whose family moved here after about 300 years on Chios, fleeing the Turkish invasion. Jacopo Barozzi da Vignola supplied the architecture and designs. A later phase around the end of the 17th century added the small theatre.

The frescoes in the piano nobile were painted by Antonio Tempesta, Bernardo Castello, Domenichino and Francesco Albani, among others. Subjects include the Giustiniani coat of arms, the fable of Cupid and Psyche, the four seasons, Mount Parnassus, and the ports of Genoa and Chios. A small ground-floor theatre, modelled on an English design Vincenzo Giustiniani had seen in Surrey, has wooden boxes and a large pit.

The main building reopened on 24 May 2016 after roof restoration and can be visited on Saturday mornings with a free guided tour. The park and the Casina di Caccia are still undergoing restoration and are not fully accessible. Access to the piano nobile is via the frescoed loggia.

The small theatre on the ground floor was modelled on English practice: Vincenzo Giustiniani had visited Henry VII's summer residence in Surrey. It has wooden boxes once hung with drapery for noble spectators, and a large pit entered from the courtyard for the general public.
