Montorio Castle was presumably a look-out post which was once part of the Verona city fortifications and which is first mentioned in documents dating back to 995 AD. It was subsequently rebuilt by the Aldobrandeschi in the Middle Ages and restructured by the Ottieri and then transformed into a fortified farmhouse after the annexation of the county in the Grand Duchy of Tuscany. Only certain sections of the structure remain, as four of the seven towers were demolished (as well as parts of the walls) by the Austrians in 1820. The castle now serves as a venue for cultural events held in the summer.
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.
