Jegerup church is a whitewashed Romanesque church with choir and nave. Two late-Gothic buildings were added later: A tower on the western side and a weaponhouse to the south. In 1905 a sacristy was added to the northern side of the church. The inside of the church is also whitewashed and the flat ceiling is in plaster with stucco, the choir arch has been changed into a pointed arch.
The alterpiece is from 1614 and was bought from Øsby Church in 1838, but had to be reduced to fit into the choir. The motive in the centre depicts the last supper and in the wings are the Binding of Isac and the Crucifixion, painted in 1769. The former alterpiece has been restored and in 1949 paintings by J. Th. Skovgaard were added. The figures from another former Gothic alterpiece from around 1400 has been preserved, and these figures are thought to be some of the oldest alterpiece-figures in Denmark. The baptismal font is a Romanesque granite font, with the base shaped as a church with two towers and three apses. The organ was made by Marcussen & Son in 1890 and restored in 1943.
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.
