Rättvik Church dates from c. 1300. It has been enlarged several times and its present shape is from 1793. The church contains some fascinating old inventory like a triumphal crucifix believed to have been made in Germany in the 14th century. There are also medieval frescoes depicting St. Olav and St. Stephen. The altarpiece depicting the Resurrection of Christ was made in the 17th century as well as the pulpit.
Around the church are 87 church stables, some are from the end of the 15th century. The stables were used to house the horses of parishioners while they attended services at the church.
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.
