The building design harkens to a classic Renaissance design likely developed by
Bramante in his design for the now destroyed
Palazzo Caprini, the home of Raphael. The home has successive layers where the degree of facade decoration matches the function of the interiors. The ground floor is rustic stone, almost fortress-like. The second floor, the piano nobile, is decorated with doric columns. The Palazzo Vidoni-Caffarelli conserves 16th-century frescoes in its
Charles V hall that depict events in the life of the emperor. The author is unknown, but described as belonging to the
Mannerist school of
Perin del Vaga. The palace also contains some 18th-century frescoes attributed to
Nicola Lapiccola,
Bernardino Nocchi,
Tommaso Conca,
Ludovico Mazzanti. The interior has some Roman statues, including a statue of emperor Lucio Aurelio Vero, and a fountain derived from a Roman sarcofagus. It also contains a marble portal decoration of the Venetian lion of St Mark from a Croatian city. ==References==
