The Palazzo Alliata di Villafranca is former aristocratic mansion, now converted into a museum, located just off Via Vittorio Emanuele (ancient Via Cassaro) facing the Piazza Bologni which opens two blocks west of the Quattro Canti intersection, in the ancient quarter of the Albergaria of the city of Palermo, region of Sicily, Italy.^[1][2][3]

By 1567, this area was part of a large garden or orchard, known as Piano d'Aragona with a large house owned by Aloisio da Bologna, baron of Montefranco. Vannino Beccadelli had arrived from in Palermo at the beginning of the XIV century. The family was later called "di Bologna", and gave the name to the piazza in front of the palace. One prominent member of this family was Il Panormita, a poet of the Aragonese court on the island. Another member was the archbishop Simone di Bologna, who is linked to the enlargement of the Cathedral of Palermo, and erection of the Archbishop's Palace. However, the son of Aloisi did not have male heirs, and by 1640, the palace was sold to the Alliata di Villafranca family, wealthy bankers from Pisa that had arrived to Palermo around the 14th century, and by 1609 had acquired the title of prince of Paruta.

The palace suffered damage during the 1751 earthquake, prompting a major reconstruction that joined the palace to adjacent houses. The work was commissioned from the architect Giovanni Battista Vaccarini, assisted by the Cascione and Ferrigno. The interior decoration included frescoes by Gaspare Serenario, Vaccarini's brother-in-law, who depicted large frescoes to the Glory of Prince Alliata and the Princess admires the Temple of Glory. The frescoes were lost after the bombardments of World War II. The fresco depicting San Dazio before the Virgin remains. During the revolution of 1820, the Palace was heavily damaged by the insurgents. The palace was owned and the main residence of the Alliata di Villafranca until the late 20th century.^[4] In the following century the palace was rebuilt to its current late 17th century appearance to designs by the architect Giovanni Battista Vaccarini.^[5]

The monumental facade, now somewhat dilapidated, has two symmetrical doors recalls the era during which the building was used by the Kingdom of Sicily's postal service, as do a number of rooms on the ground floor.^[6] The two large stucco coats of arms by Giacomo Serpotta show the heraldic arms of the Alliata as Princes of Villafranca.^[1] A plaque on the centre of the main facade recalls Giuseppe Garibaldi's stop in the building in 1860:

In questa illustre casa

il 27 maggio 1860
per sole due ore
posò le stanche membra
GIUSEPPE GARIBALDI
---
Singolare prodezza
fra l'immane scoppio
delle micidiali armi di guerra
sereno dormiva
il genio sterminatore

di ogni tirannide

The interior salons of the palace do not reflect the dilapidated exterior; the palace houses one of the city's main art collections, including The Stoning of St Stephen and The Tribute Money (both painted in 1639 by Matthias Stom), a Crucifixion by Anthony van Dyck, the 1791 Birth of Prince Giuseppe Alliata Moncada, son of Prince Fabrizio Alliata Colonna and Giuseppina Moncada Branciforte, with Abundance and Fame and with the Genius of Palermo Paying Homage by Desiderio De Angelis, Saint Joseph with the Christ Child (attributed to Pietro Novelli) and works by Francesco Lojacono, Mario Rutelli and Filippo de Pisis. The documents commissioning the Van Dyck are still in the family archive. As well as paintings on canvas and card, the building's art collections include drawings, prints and stucco medallions. The building's furnishings include mirrors, Murano glass chandeliers, elaborate over-doors, maiolica flooring (including the family coat of arms), furniture, vases, works in silver, bronze, porcelain and ceramic, classical archaeological finds, wax sculptures, geological samples, marble helmets and shields, lace and embroidery.
