Østermarie Church was originally built in the early 13th century. While it was being demolished in 1890, it was discovered it was of considerable architectural interest and work was stopped. The new church from 1891 is also in the Romanesque style.
The new church was built on the place where the old church tower once stood. The architect was Andreas Clemmensen who was involved in the design of Christiansborg Palace. Built in the Romanesque style, it consists of a tower, nave, chancel and apse together with two cross pieces. The outer wall is granite from the nearby Paradis quarry.
The rear wall of the altar is topped by seven candles in a seven-armed candlestick. The limestone font (ca. 1250), in late Romanesque style, comes from Gotland. The pulpit has four carved panels in oak from 1593. In the northern cross arm, there is an epitaph to Jens Kofoed, popularly credited with the liberation of Bornholm from the Swedes in 1658. The cross below the chancel arch, added during the church's restoration by the architect Rolf Graae in 1964, is the work of Paul Høm, a local artist.
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.
