Montuenga Castle in Soria, Spain forms part of the defensive line of the Jalón River set in a natural passage between the plateau and strategic basin of the Ebro. The area was subject to disputes, notable during the Castilian Civil War.
The castle is perched on a high hill, steep and long, from which it dominates the town of Montuenga de Soria. The remains of the building, two polygonal towers at each end, are joined by walls.
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.
