In 1842 the palace was acquired by Prince Marino Torlonia, who commissioned the restoration to Antonio Sarti, extending the front over Via Bocca di Leone.

The fountain is inserted within an architectural element with side pillars, surmounted by an arch with the coat of arms of the Torlonia family between two lions rampant.

Alessandro Torlonia, 5th Prince di Civitella-Cesi, lived in the palace from the time of his marriage with the Infanta Beatriz of Spain until his death in 1986.

After Alessandro's death, Beatriz sold her part to her son-in-law Paul Annik Weiller (the father of Princess Sibilla of Luxembourg) and Francis Alexander Shields (the son of princess Marina Torlonia di Civitella-Cesi and father of actress Brooke Shields), sold his part to the architect Renato Bocchi.

Later Paul Annik Weiller also sold to Bocchi his part with a condition that princess Beatriz Torlonia could remain in the palace until her death.
