Holy Transfiguration Church is an Orthodox church in Kėdainiai. The first, wooden Orthodox church was constructed in 1643. From 1652 it belonged to an Orthodox monastery of the Holy Transfiguration, which was destroyed by fire in 1771. After this event the monastery was never rebuilt and the monks moved to the Holy Spirit Monastery in Vilnius. In 1798 it was officially closed. Despite the advice of the Holy Synod of the Russian Orthodox Church, the remaining church was not made a parish church because of the tiny number of Orthodox Christians living permanently in Kėdainiai. The services were held there only occasionally, wherever a Russian military unit arrived to the town.
In 1841 this situation changed together with the arrival of more Russians to the town. In 1895 the church also turned out to be too tiny and it was replaced by the one which was preserved up to today. During World War I, the church was abandoned. Only in 1918 new parish clergy arrived to Kėdainiai. It was registered as an active parish by the Soviet government in 1947, with 230 parishioners at this moment.
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.
