The Roman Catholic Church of St. Nicholas is the second oldest Roman Catholic church standing in Kyiv, the capital of Ukraine after the St. Alexander Roman Catholic Cathedral. Today the building is shared between the Roman Catholic Church of Ukraine and the National Organ and Chamber Music Hall of Ukraine.
It was constructed in 1899–1909 and was built by the Latin Rite Catholic community in a Gothic type construction, by architects Władysław Horodecki and Emilio Sala. It stands at vulytsia Velyka Vasylkivska (Greater Vasylkiv street) in Pechersk Raion next to the Kyiv National Linguistic University between the National Sports Complex Olimpiysky and the Railroad station Kyiv-Tovarny.
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.
