The history of the Czchów Castle dates back to the 13th century, when a Romanesque watchtower was built here. In the 14th century, a defensive castle was added to the tower. It became the residence of the Czchów starostas, and was destroyed in the Swedish wars of the mid-17th century. Finally, the castle lost its military importance, and was turned into a prison, which was closed in 1772, after the first partition of Poland. Currently, the only remaining parts of the complex are a 14th-century tower and foundations of the defensive wall.
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.
