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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
