Dieleghem Abbey was founded in 1095 by the Bishop of Cambrai and administered by Augustinian canons. In 1140, the abbey’s monks switched to the rules of the Premonstratensian order. In the 13th century, the abbey now called Dieleghem possessed half of the commune’s territory and played an important social and economic role until the French Revolution. In November 1796, the Canons Regular were evicted and deported to an island off the shores of Brittany.
The abbey was looted and subsequently destroyed, sparing only the abbot's residence. The former residence of the abbot now houses the collections of the museum of the County of Jette.
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.
