 During the 18th century the palazzo formed the centre of a family complex of properties which were rented in their entirety to the Stuarts, pretenders to the British throne; thus for a time the palazzo was the home of a court in exile.In 1909 the palazzo was heavily restored which has changed de' Rossi's architectural concept of the original design by removing the pediments to the windows and the statuary decorating the roofline.The 17th and 18th century interior decoration of the palazzo has been preserved complete with their frescoed ceilings.
