The northernmost Medieval stone church of Norway, situated in the vicinity of Harstad. Though frequently mentioned as a 13th century church, it was probably completed shortly after 1434 (dating based on dendrochronology). This early dating is based on historical indications. Compared to the other 10 north Norwegian Medieval stone churches, Trondenes church is well preserved and the exterior is close to the original state. The nave is 22.6 m long and the chancel is 13.5 m, 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.
