Christiansø church was first consecrated in 1685 when the island's fortifications were completed. Serving the garrison, it was initially located in a small floor room in the fortification tower where it was used until 1821. It was then moved some two hundred metres to the east to its present location on an irregular quadrangular plot surrounded by fieldstone walls.
The small rectangular granite building was rebuilt and enlarged in 1852, a porch being added on the western side. Comprehensive restoration work was undertaken in 1928 under architect Christian Olrik. The main entrance was widened and a gallery was added inside. The four straight-sided windows on either side of the nave were slightly reduced in size and given a rounded finish. The ceiling consists of a plastered, wooden barrel vault.
In the south-west corner of the churchyard there is a free-standing bell tower with two bells. Typical of the Bornholm style, it consists of a fieldstone base and a half-timbered belfry.
References:Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
