The Château de Fontaine is a chateau in the municipality of Onhaye, Wallonia. It is located south of the village of Anthée. It replaced a medieval castle, of which there are remains in the north east corner. It was the seat of the lordship of Fontaine, which included Anthée, Morville and Miavoye, spanning the counties of Namur and Agimont in the Prince-Bishopric of Liège.
The chateau is built of limestone, and is U-shaped, open to the south, with towers on each corner. There is a farm to the east with the same plan, with the open side facing the chateau. The two-story chateau was probably built in stages in the 16th century. The other buildings were erected in the 16th and 17th centuries. The chateau was renovated in neo-traditional style between 1907 and 1909. The chateau was given a uniform appearance, with the towers raised and the present windows and other decorations added.
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.
