Keminmaa old church is northest medieval church in Finland (built in 1520-1553) and one of the latest ones built before Reformation.
The paintings on the ceiling depict the sufferings of Christ; they date from 1650. The pictures of saints on the walls, the baptismal font and the holy-water font date from the Catholic times. The bier and stocks located in the church porch as well as the black pew standing inside the church itself remind us of the old parish tradition.
The fame of the Old Church of the Parish of Keminmaa is mostly based on the Lutheran priest, Nikolaus Rungius. He was the vicar of Kemi church during the Thirty Years War. Nikolaus Rungius died in 1629 and he was buried under the church in the tradition of the times.
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.
