Thurant Castle (Burg Thurant) was built in 1198-1206 by Heinrich Pfalgraf Guelphs. It was besieged in 1246-1248 during the war between Trier and Cologne archbishops. After the war the castle was interestingly divided to two parts, Trier tower and Cologne Tower. Both sides had a separate entrance and living buildings. In the 19th century the castle was left to decay, but restored in the 20th century.
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.
