Eidsborg Stave Church is one of the best preserved Norwegian stave churches. The church was probably built between 1250-1300. The church is dedicated to the traveller's patron, St. Nicholas of Bari. It was partly reconstructed in the 19th century. The chorus was demolished in 1826. The new choir dates to the period 1845-50. The reconstruction work did not affect the structure or the shape of the church. It was restored in 1927 when painted figures and ornaments dating from the Renaissance and old murals from the 17th century were revealed.
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.
