Ivetofta Church was probably built in the 12th century, the tower (built in stone and decorated with carved sandstone) on the western side being added in the 13th century. The altar, pulpit, pews and the baptismal font were donated by Sophia Brahe in the early 17th century, who had moved to the area with her second husband and was known for her work in Danish genealogy. These features have been retained in the renovated church. Brahe had planned on being buried there but returned to her native Denmark, settling in Helsingør before she died. Her planned headstone is on display at Ivetofta church.
Major extensions were completed in 1850s in order to accommodate a growing population in the town. The old nave and chancel were demolished and a wider church room with cross arms and a three sided chancel were built by the architect C. G. Brunius. The nave was extended to form two arms of the cross. Major external renovation work was carried out in 2012, which retained features added by Brahe. The porch has the flooring that was removed from the coal cellar of the old church.
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.
