The first church in Håtuna was probably built in the 1000’s. Later in 12th century it was replaced with a small Romanesque-style stone church. Oldest parts (like the tower) were included to the present church, which was built in the early 14th century. The brick vaults were made in the 15th century. The steeple collapsed in 1700 and the remaining parts of the tower was demolished during the 1800s. During the restorations in 1873 and 1919-1920 the church was partially reconstructed.
The interior is very rich. There are for example baptismal fonts from the 1200’s, a triumphal crucifix made in the 1300’s and eight wooden sculptures from around 1450 and descended from a medieval altarpiece. There is also a runestone (U 660) erected in the porch (moved there in 1932).

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.
