Marchenilla Castle was built during the times of Muslim domination, in the 11th and 12th centuries, although after the Reconquest by Ferdinand III is when it acquired its definitive layout. Important development was still taking place right up to the late 15th and early 16th century.
The Castle is located on a promontory which is high enough to completely dominate the surroundings, in the same place as previous human settlement was to be found in the Bronze Age.
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.
