St. Clement's Church (Klemens Kirke) is a parish church located in the village of Klemensker on the Danish island of Bornholm. Completed in 1882 in the Historicist style, it replaces an earlier Romanesque church from the 14th century or earlier. Today the church is noteworthy for works contributed by the Bornholm artist Paul Høm. Many items of inventory from the old church can now be seen in the Bornholm Museum. The church is named after St. Clement of Rome, Latin: Clemens Romanus, as documented in early references from 1335.
Several runestones have been found in the vicinity. They probably date from the 11th century when a wooden church may have stood on the site. Now standing on the south side of the church, the Lundhøj Stone (found in 1819 as a bridge over a brook) is 2.74 meters tall. There are many other fragments of runestones bearing one or two words, some forming part of the churchyard wall.
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.
