The church of Björklinge was built originally in the early 14th century. It was enlarged in the 15th century and the present appearance originates mainly from the restoration made in 1655. The church contains a triptych and a sandstone font made before the Reformation. There are five stained glass windows made in 1658. The current altarpiece was carved in 1714. The church has also a rare 18th century organ, which has been newly restored. Guided tours are available when the church is open.
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.
