The oldest part of the presently visible church at När is the tower, erected at the middle of the 13th century. Originally, it was designed to be able to function as a defensive tower, with arrowslits still visible on the first floor. The present nave and choir of the church were added to the tower around the year 1300. Of an earlier, Romanesque church on the same site no traces remain today.
Externally, the church has two portals decorated with stone sculptures on the southern façade. Internally, the nave is divided in two by two central columns. Among the furnishings, the Romanesquebaptismal font is the oldest. It was made by the sculptor known as Hegvald and its sculptured reliefs display religious motifs. The church also has a late medieval triumphal cross. Other furnishings are mostly from the 17th and early 18th centuries. In one of the lychgates leading to the church, a decorated tombstone from 1322 is displayed.
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.
