After the end of the Farnese family rule of Parma, much of the movable assets of the palace were removed by then Duke Charles I, later King of Spain, and taken to Naples in the 1730s.
In the second half of the nineteenth century, the Reinach Theatre was built on the area of the previous church of San Pietro Martire, inaugurated in 1871.
In 1939 it changed its name to Teatro Paganini and was almost completely destroyed, along with parts of the palace, by an aerial bombardment in May 1944, and then demolished.
Between 1986 and 2001, after a long and debated planning phase, the redevelopment of the Piazzale della Pace was completed on a project by the Swiss architect Mario Botta, creating the large garden and the fountain that follows the perimeter of the former church of San Pietro.
