Varberg Church was completed in 1772, as a replacement of an elder church from 1687 that was destroyed in a fire on 18 May 1767. The interior of the church is neoclassical. Mostly of it is from the 19th century. The retable is from 1816. The pulpit was set in during a restoration of the church in 1890–1891. The wooden baptismal font has seven edges. It was made from oak in the 17th century. It comes from an elder church that was destroyed in a fire on 12 August 1666. At this time, the city of Varberg was situated in an area called Platsarna. The city was moved to its current location after the fire in 1666. A sacristy was built to the north in 1961.
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.
