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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
