Bornem Castle, also known as the De Marnix de Sainte-Aldegonde Castle, stands on the Oude Schelde, a tributary of the Scheldt. The earliest fortification on the site was of the 10th or 11th centuries and was intended to defend against the incursions of the Normans. A later castle was built on the foundations of the older building in 1587 by the Spanish nobleman Pedro Coloma, lord of Bobadilla, a follower of Alexander Farnese. The property was afterwards leased by the family de Marnix de Sainte-Aldegonde, who became the outright owners in 1773.
The present house was built on the same site at the end of the 19th century to plans by Hendrik Beyaert, after the remains of the 16th century building had been demolished. It remains in ownership of the house Marnix de Sainte-Aldegonde, the current resident is John de Marnix de Sainte-Aldegonde, 14th Earl of Bornem.
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.
