Located in the extreme north of the province of Segovia, Fuentidueña village rises above a narrow valley formed by the Duratón River, a unique geographical location that explains the importance of the town during the Middle Ages. The Villa was walled on its north, south and west sides with a clearly defensive function. On the other hand, there is an impressive rock cut that makes defense very easy. Intramural access is only possible through one of its three doors.
There is no historical facts about the origin of castle, but it seems that its construction dates back to the 12th and 13th centuries. It had importance with the reign of Alfonso VII, who had Cortes here and peace was concluded with Navarra and granted testament in 1204.
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.
