Medieval church dating from approx. 1250. The south chapel with the interesting frescoes is added approx. 1500. The north chapel is built 1686 and reconstructed 1785. The tower at the south chapel is built 1789. Porch, sacristy and stair tower is built in 1881-82.
The Duke to Nordborg Castle built a chapel in 1700 at the east end of the church. This chapel is the final resting place for the ducal families and their coffins are still standing in the room behind the altar. If the wooden door is closed you may open it and look through the grated door at the coffins, a list of who is laying in the coffins is found on the wooden door.
The pulpit, carved by Jørgen Ringnis is from 1626. The crucifix in the choir arc dates from approx. 1500. The altar made in 1655 is presumably from Flensburg.
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.
