Bjernede Church is one of only eight round churches in Denmark and the only one of its kind on the island of Zealand. The present church was built in circa 1170 by Sune Ebbesen from the influential Hvide family who belonged to the circle around King Valdemar II. His father, Ebbe Skjalmsen, the uncle of Bishop Absalon, had previously built a wooden church at the site. The tower of Sune Ebbesen's round church contains a room which the Hvide family used as an assemblage hall.
The lower part of the church stands in granite while the upper part is made of brick, a relatively new material at the time which had only been used in Denmark since the 1140s. The inspiration for the design most likely came from Schlamersdorf Church in Wagria which Sune Ebbesen had visited several times as a military commander. Bjernede Church, Horne Church in Jutland and Thorsager Church on Funen are all built to the same floor plan as that of Schlamersdorf Church. Four interior granite columns support the roof structure. Theporch was built in about 1500 and the tower had previously been altered but was, between 1890 and 1892, changed back to its original design by Hermann Baagøe Storck.
Storck was later heavily criticized for his restoration work. Peder Vilhelm Jensen-Klint and Ivar Bentsen later made church projects which resembled Bjernede prior to Storck's intervention, when it had a Bishop's Hat-like roof. Storck's restoration came to mark a turning point in Danish restoration architecture which from then on applied a more sensitive approach to the restoration of historical buildings.
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.
