Stråvalla Church was built approximately between 1100-1350. The stone church represents the Romanesque style. The weathervane is signed with year 1671 and the belfry was erected in 1739. The interior contains mural paintings that were made in the early 1500s. The original font from the 13th century is located to the Statens historiska museer in Stockholm. The font in the church dates from the 14th century. The pulpit dates from the mid-18th century.
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.
