Vätö Church is mentioned in written sources for the first time in 1337 and was built earlier in the same century. The vaults supporting the ceiling were constructed in the 15th century. They are profusely decorated with frescos in a style reminiscent of Albertus Pictor and probably dates from the last quarter of the 15th century. The church porch was also built at around the same time. Among the church furnishings, the baptismal font is unusual and originally belonged to Nydala Abbey in Småland. The church also has a 16th-century wooden sculpture depicting Saint George and the Dragon, a piece of art inspired by the Saint George and the Dragon in Stockholm made by Bernt Notke. A triumphal cross that earlier belonged to Vätö Church is today on display at the Swedish History Museum.
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.
