Bornem Castle, also known as the Marnix de Sainte-Aldegonde Castle (Dutch: Kasteel van Bornem, or Kasteel Marnix de Sainte-Aldegonde), is a country house, formerly a castle, located in Bornem, province of Antwerp, Belgium.
The earliest fortification on the site was of the 10th or 11th centuries and was intended to defend against the incursions of the Vikings.
A manor house was built on the foundations of the older building in 1587 by the Spanish nobleman Pedro Coloma, Baron of Bornhem and lord of Bobadilla, a follower of Alexander Farnese.
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.
