In 1459 the market town of Poběžovice was bought by a lower nobleman Dobrohost of Drštka by Skořice na Rokycansku. At the latest in 1470, he left the keep and had built a late-Gothic solid water castle called Nový Ronšperk ('New Ronšperk'). Since then he was known as Dobrohost of Ronšperk, and Poběžovice was renamed Ronšperk. In 1864, the castle and the manor were bought by the noble family Coudenhove, later known as Coudenhove-Kalergi family.
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.
