Castle of the Princes de Mérode, also called as 'old castle', has been the home of the House of Merode since more than five centuries. The central keep or Donjon was built in local brown stone in the 14th-century. It probably replaced an older fortress on the same spot. Other parts of the building date from the 16th century. The castle was adapted, extended and restorated several times. From the 16th century onwards it was transformed into a more luxurious noble dwelling and gradually lost its fortified character. Several restorations in the 19th century gave it back a more romantic medieval appearance.
The sumptuous interiors contain fine furniture, paintings, tapestries, and objects collected by the Merode family throughout the centuries. The most important rooms like the entrance hall, the knights hall, the large drawing room, the dining room and the chapel can be visited during the 'Kasteelfeesten' in the first weekend of July.
An English landscape park of 12 hectares surrounds the castle. The ponds in the park are connected with the moat of the castle. Across the Nete river there is a larger formal park (60 hectares) in the French tradition with a rectangular pond forming a large perspective. It was commissioned by Fieldmarshall Jean-Philippe-Eugène de Mérode-Westerloo at the beginning of the 18th century and was inspired by Versailles.
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.
