During the 18th century this entire range of buildings was, by courtesy of the pope, the residence of the House of Stuart government in exile in Rome.

The architect was Mattia de Rossi who had been commissioned to build a residence for Giovanni Battista Muti Papazzurri, a member of one of Rome's patrician families.

The principal facade, today painted ochre and decorated only by quoining is of just three bays, with the main entrance to the palazzo, leading to an inner courtyard, at the centre on the ground floor.

An 18th-century drawing of the building (left) shows the top floor was originally lower and decorated in the Baroque style with statuary.

The palazzo then passed through female descent into the family of the Marchese Livio Savorelli,[2] who assumed the additional names of Muti Papazzurri.

[5] By 1850 the painting (sometimes called the "Mater Misericordiae" had overcome her distress at the invasion of the Vatican states and was now performing miracles involving divine intervention.

The Muti Papazzurri are buried in Rome at the Church of San Marcello al Corso, where their Baroque tombs and memorials still exist.

[7] The Popes Clement XI and Innocent XIII considered the couple to be the rightful and, more importantly, Catholic King and Queen of England, Scotland and Ireland.

The cousin of Pope Innocent XIII, Francesco Maria Conti, from Siena, was here the Gentiluomo di Camera (Gentleman of the Bedchamber) in the little Roman Jacobite court.
