The original Hainewalde water castle, built under rule of the family von Nositz, was located north of the terraces of the new castle. The only remain of the old water castle, which was demolished in 1780, is the gate lodge with his west-side Renaissance-portal. Schloss (New Castle) was constructed in 1750–1753, along with its Baroque gardens, under the rule of the Kanitz-Kyaw family. It was renovated in 1883, the Baroque elements on the outside façade removed and replaced by 'Italian'-style sgraffito.
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.
