St. John's Church was built between 1891 and 1894 in the Gothic Revival style. With 1250 seats, it is the largest church in Bergen.
In 1888, an architectural contest was conducted for the design of a new church. It was built from drawings by architect, Herman Major Backer (1856–1932). The frescoes in the Church's ceiling date from 1924 and were completed by Hugo Lous Mohr (1889-1970). The building process was first lead by architect Adolf Fischer and from 1891 by Hans Heinrich Jess. The church was consecrated in 1894.
The organ was built by Schlag and Sohn of Wurttemberg. It was modernized by JH Jørgensen of Oslo during 1967. The altarpiece depicts Christ in prayer and was designed in 1894 by Marcus Grønvold. The church tower is the highest in the city at 61 metres. The main tower has four stair towers and a carillon. It was designed by Verein Bochum in Bochum, Westphalia.
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.
