Palazzo Marchesi is a former aristocratic palace located on Via Santissimi Quaranta Martiri al Casalotto #14, adjacent to the Chiesa del Gesù for which this palace houses a bell-tower, in the ancient quarter of Albergheria, in central Palermo, region of Sicily, Italy.
The palace contains elements of this construction in the Gothic-style windows of the lower bell-tower, while the courtyard arches exemplify a more sober early-Renaissance style.
By 1518, the Salvatore Marchesi, a prominent minister in the Aragonese Viceroy's service purchased the palace from the Cusenza family.
The Marchesi family sold the palace in 1556 to the government, who installed the Holy Inquisition tribunal in the building for two years.
Underneath the courtyard was a large excavated room, that now has been identified as either or both a camera dello scirocco for cooling off in the summer or as a former “Miqweh” belonging to the Jewish community.
