Stuyvenberg Castle is a residency of the Belgian Royal Family, located in Laeken, Brussels. It was built in 1725, acquired for 200,000 franks by the Belgian State in 1840, and later bought by Leopold II who donated it to the Royal Trust. It is near the Royal Palace of Laeken, the official residence of the King and Queen of the Belgians.
The first Belgian King Leopold I used the castle for his mistress Arcadie Meyer-Claret, and their second child Arthur was born there in 1852. Later, it was the birthplace of King Baudouin in 1930 and Albert II in 1934; both spent their early years at Stuyvenberg. After World War II Elisabeth of Bavaria, widow of King Albert I, lived at the castle until her death in 1965. Subsequently it was used for almost three decades as a guest house for foreign dignitaries. From 1998 to 2014 Queen Fabiola, widow of King Baudouin, called it her home. She died at Stuyvenberg on December 5, 2014.
The residence has also been home to Princess Astrid of Belgium, the sister of the current King Philippe.
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.
