The church of the Holy Spirit located within the boundaries of Sant'Orsola cemetery. 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.
References:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
