Tavigny Castle dates to th late Middle Ages, and it may have been only a refuge tower that is now the central part of the castle. Its walls are long 10 meters, thick 2 meters and they had plenty of arrow slits. The lordship of Tavigny belonged at first to a family who wore already its name, but in 1360, it was already owned by the Ouren family, a powerful Middle-age family from the dutchy of Luxembourg. The central tower that was enclosed in walls with round towers in the corners got transformed little by little in a seignorial residence. The narrow windows and the arrow slits got substituted by large great picture windows and they made a very nice Louis XIII style ensemble
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.
