Norra Fågelås Church is first mentioned in 1225, but it has probably been built already in the 1100s. It was largely restored in 1650s. The Stackelbergska family grave chapel was added 1749 and the next restoration was completed in 1754. The cruficix from the 1400s is today in Stockholm Historical Museum. the font is made of sandstone and donated to the church in 1651 by M.E. Sparre of Almnäs Castle. The pulpit dates from 1667.
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.
