The Church of St Paraskeva is a Bulgarian Orthodox church in Sofia. The church, dedicated to Saint Paraskeva, is located on 58 Georgi Rakovski Street in the centre of the city. It is the third-largest church in Sofia.
Plans to build a church at the site date to 1910, when Stuttgart-educated Bulgarian architect Anton Tornyov (1868–1942) won a competition for the church's design. Due to the Balkan Wars and World War I, however, the construction was postponed. In 1922, the church board of trustees announced another competition, which was again won by Tornyov. The construction of the Church of St Paraskeva was complete by 1930, but the finishing works on the porticos did not cease until 1940.
St Paraskeva has a somewhat unusual design for an Eastern Orthodox church. For example, the cella is in practice a round chamber over 20 metres in diameter. The cella gradually disintegrates into the surrounding apses.
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.
