Backenkyrkan or Backen Church is the oldest church in Umeå. There was a wooden church probably already in the 13th century. In the late 1400s the archbishop of Uppsala ordered to replace it with a stone church. The current church was built between 1501-1508. Backenkyrkan was damaged badly by fire in 1893 and again in 1986, when the wooden interior was completely destroyed. The church was restored and reinaugurated in 1990.
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.
