From 990 AD, Château de Castelnou served as the administrative and military capital of the Viscount of Vallespir. Its irregular pentagonal plan follows the rocky outcrop on which it was built, this elevated position providing defence against enemy attacks.
The castle was taken by the troops of James II of Majorca en 1286, and again in 1483. Largely demolished in 1559, it was no longer restored or inhabited and deteriorated throughout the 17th and 18th centuries. At the time of the French Revolution it became the property of the commune. It was sold to Viscount Satgé in 1875 and, by 1900, had become again an elegant and habitable fortress. It was acquired in 1946 by Charles-Emmanuel Brousse who was married to Amy Elizabeth Thorpe, a famed American spy. Having been ravaged by a terrible fire, in 1987 it was sold and has since been restored.
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.
