Bleijenbeek Castle was built of bricks around 1300. According to the 19th-century historian A.J. van der Aa, the castle is known for its numerous sieges by the armies of Guelders and Spain. In 1580, the castle was besieged by the forces of Guelders, but it was defended bravely by the lord of the castle, Marten Schenk. When the Duke of Parma sent cavalry, the besieging army had to retreat. In 1589, Schenk changed sides, and the castle was besieged by Marcus van Rije, the stadtholder of Guelders appointed by the Spanish king; this time, the castle was conquered.
The castle has lain in ruins since the bombardment by the British RAF on 21 and 22 February 1945, during Operation Veritable. In 2009, the property was purchased by the Bleijenbeek Foundation, which intends to restore the remaining structure, moat, and surrounding gardens and provide public access after work is complete. Construction began in the summer of 2012.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
