The feudal lord Matteo Sclafani, Earl of Adernò, was in constant competition with his brother, who built Palazzo Chiaramonte.
Sclafani's response to this was precisely to raise close to the Norman Palace the Scalfani Palace, in 1330.
In 1435 he found instead that the town hospital has changed its original face, and in 1832 was later converted into barracks. 

The building has been announced by the fresco of the Triumph of Death, which was released in '400 in her backyard.
Currently, the painting is kept in the Regional Gallery of Palazzo Abatellis and was recently restored. 
It is not known who was the performer, but it is very interesting in style, enriched with Hispanic, Flemish and Italian influences. At the centre of the composition, under the picture of Death riding a skeletal horse, lie eight corpses, each shot with an arrow of extermination. Among the corpses are recognized below, from hats and crowns, two popes (or a pope and antipope), a bishop and a king.
We recognize some of the verses of Petrarch’s Triumphus Mortis and the iconography of death that comes on a horse draws the Apocalypse of St. John the Evangelist. On the left there are eight humble figures, maybe hermits, beggars or cripples; they are also a total of eight and their social status is in contrast to that of the eight powerful annihilated by death. The artist's intention is clearly to emphasize that we are all equal in death, no one will be spared, to be rich or poor.
