The oldest parts of the Ånimskog church (a square floor area) were built in the early 13th century by an unknown master. In the beginning of the 17th century the eastern gable was removed and the church was enlarged to the east.
The roof paintings were completed in 1739 by Hans Georg Schäffner. The font, made of sandstone, date from the 13th century. The red wooden bell tower was built in 1731.
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.
