chiesa del Santo Spirito (Church of the Holy Spirit)

The Cistercian monastery was founded between 1173 and 1178 by the archbishop of Palermo, Walter of the Mill, and was entrusted to monks of the calabrese Abbey of Sambucina. Considerable donations of King William II of Sicily and his mother, Margaret, enriched the monastery's property.
On March 30, 1282, it was in front of this church that the popular insurrection, later named the Sicilian Vespers, exploded.
