Leven Church was built in the 11th century as a manor chapel for the near Levene manor. It was enlarged in the 1600s by J. H. Reuter. The font and small bell date from the original church.
Levene church has royal connections. Three sisters of King Carl Gustav were confirmed at this church. Governor Johan Hindrikson Reyter greatly assisted the expansion of the church in the 17th century and had a family crypt built. The church is particularly known for its unusual twin steeples. The largest runestone in Sweden is today situated on the churchyard.
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.
