Dominating the southern side of Tito Square is the imposing Praetorian Palace, which has served as the municipal seat for some eight centuries. Its Venetian Gothic design dates from the middle of the 15th century, with the outer staircase and balustrade added fifty years later, and the overall appearance of the façade taking shape in 1664 after significant renovations. After serving various purposes following the downfall of the Venetian Republic at the hands of Napoleon in 1797, the building underwent a decade long restoration in the 1990s and now once again serves as the municipal seat and mayor's office, as well as the Tourist Information Centre.
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.
