The present Anundsjö church was built in 1437 and is a good example of northern late medieval church architecture. It has a simple rectangular floor plan and consists of nave, porch to the south and the vestry in the north. The church is constructed of stone with a roof covered with thick wood paneling. Entrance is through the porch. The church still has its medieval appearance. The church has paintings on the ceiling that were previously painted over with white paint. The original paintings were revealed in a restoration in 1952.
The bell tower was built in 1759 by Per Zakrisson (1723–1780) of Anundsjö. Zakrisson was a craftsman, carpenter, wood carver, blacksmith, and mechanic. He was most noted as a church builder. Above the belfry stands a memorial to him set up in 1959 for the 200th anniversary of the building of the tower. The tower has two bells.
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.
