Industrial Frenchman Pierre Bardou-Job became wealthy selling rolling paper and decided to have a château built for each of his three children. All designed by the Danish architect Viggo Dorph-Petersen, the Château d'Aubiry was for his son Justin and built from 1893 to 1904. Pierre Bardou-Job himself never saw it, as he died suddenly in 1892 just before the start of the construction. The palace has an Art Nouveau style interior. The English park has pavilions, a swimming pool, terraces and greenhouses.
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.
