Trondenes Church is the northernmost medieval stone church of Norway. Though frequently mentioned as a 13th-century church, dating based on dendrochronology places its completion shortly after 1434. Compared to the other ten north Norwegian medieval stone churches, Trondenes church is well preserved and the exterior is close to the original state. The nave is 22.6 metres long and the chancel is 13.5 metres, making it one of the largest medieval churches of rural Norway. In the late Medieval period, Trondenes served as the main church centre of Northern Norway.
The church is especially known for its rich decorations, including three gothic triptychs, one of which is made by the German Hanseatic artist Bernt Notke. The baroque pulpit is equipped with an hourglass to allow the minister to time long sermons. The organ dates from the late 18th century. In the choir section, one can see remnants of medieval frescoes.
The church is probably the third church on the site, the first stave church was built in the 11th century, the second in the 12th. The second church was fortified with stone walls and ramparts, remnants of which can be seen around the church.The church used to have a little turret, which was demolished. Now the bells are rung from a little tower in the graveyeard.
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.
