Nederluleå church is the largest medieval church in Norrland. It was built during the 15th century and inaugurated by Archbishop Jacob Ulfsson in 1492. The church has a very rich interior and furnishings. The late-mediaeval frescos in the chancel were by the school of Albertus Pictor.
The richly decorated triptych was made in Antwerpen around 1520 and it is one of the finest in Sweden. The font and cruficix date also from the late Middle Ages. The wooden pulpit was carved by Nils Fluur in 1712.
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.
