St. Quentin Cathedral in Hasselt was granted to a cathedral in 1967, but its construction began already in the 11th century. The first church was built inthe 8th century and rebuilt in Romanesque style in the 11th century. The cathedral construction continued several centuries. In the 15th century the choir was rebuilt. During the iconoclasm the tabernacle and statues, the altar lateral and the main altar were destroyed. The tower of the present church dates from 1725; it was restored in the 19th 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.
