Finland was a part of Sweden until 1809, and the national parish of the Finnish Church was established in Stockholm in 1533, at the time accommodated in the old abbey of the Blackfriars. A building constructed on the present site 1648-1653, originally intended for ball games, and thus called Lilla bollhuset ('Small Ball House'), but mostly used as a theatre, was taken over by the Finnish parish in 1725 from when the irregularly shaped building stems. In the interior, the organ loft still resembles the gallery of the old Boll House. As the church never had an accompanying graveyard, the Church of Catherine on Södermalmwas of great importance to the Finnish parish until the 19th century.
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.
