At the end of the 18th century, a majestic building was incorporated into Las Ramblas, the palace of the Virreina, a building that, beyond its outstanding Baroque architecture, hides the sad story of a woman, Mª Francesca Fillever i de Bru, by whom You will know this building as Palacio de la Virreina.
From a wealthy family Francisca was raised in the Fiveller palace along with her 6 brothers, this family palace was in the street of la Mercé and belonged to the parish of Santa Maria and with this connection Francesca entered the monastery of Santa Maria de las Jonqueres .
In 1777 Francesca falls in love during a visit with the brother of one of her religious companions, Antonio Rocabertí nephew of the Viceroy of Peru. When he was 20 years old, he promised himself and left the monastery.
On the day of the wedding Antonio leaves her and tells the legend that her uncle Manuel d'Amat and Junyet, before such humiliation proposed marriage to her on the altar where they left her, accepting this marriage with the Viceroy of Peru that already had 70 years old
A year before, in 1776, Manuel de Amat y Junient, Marquis of Castellbell, returned to Barcelona with a great fortune, after ceasing in his position as viceroy of Peru, which he had held since 1761. As a sign of his wealth, he had this sumptuous palace mix of baroque and rococo decoration. It was built between 1772 and 1778 and, after the premature death of Amat, was occupied by his widow, Maria Francesca de Fiveller and de Bru, for what was known as the Palace of the Virreina. The plans already existed in the year 1770, but it is not known with certainty who designed them, being attributed to Josep Ausich.
The works were directed by the architect and sculptor Carles Grau (1717-1798). The sculptor Francesc Serra, who died in the work, also intervened.
It seems that the viceroy himself, from Peru, gave detailed instructions for its construction and possibly decided in a personal way the style of the façade, of Montjuïc stone and of Santanyí.
