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:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
