Øsby Church is a large, white village church, which was remodelled into a Gothic long church. You can see the remains of the original 13th century church at the bottom of the east wall. The current church was built in the 16th century.
The church has large, Gothic windows to the south, giving the church a bright and airy space with four sets of rib vaults. The ribs are decorated in Gothic frescoes, and on the northern wall of the nave there is a fresco of Saint George fighting the dragon. The beautiful carved pulpit dates from 1559.
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.
