Gylen Castle was built in 1582 by the Clan MacDougall. Gylen was only occupied for a relatively short period of time. The castle was besieged then burned by the Covenanters under General Leslie in 1647 during the Wars of the Three Kingdoms.
In May 2006 a restoration of the castle was completed with a £300,000 grant by Historic Scotland and £200,000 raised by worldwide members of Clan MacDougall.
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.
