The St Nicholas Orthodox Cathedral is the largest Eastern Orthodox cathedral in Western Europe. The cathedral was opened in 1912, thanks to the generosity of Russia's Tsar Nicholas II.
Beginning in the mid-19th century, Russian nobility visited Nice and the French Riviera, following the fashion established decades earlier by the English upper class and nobility. In 1864, immediately after the railway reached Nice, Tsar Alexander II visited by train and was attracted by the pleasant climate. Thus began an association between Russians and the French Riviera that continues to this day.
The cathedral, consecrated in December 1912 in memory of Nicholas Alexandrovich, Tsarevich of Russia, who died in Nice, was meant to serve the large Russian community that had settled in Nice by the end of the 19th century, as well as devout visitors from the Imperial Court. Tsar Nicholas II funded the construction work.
After 1917, Communist persecution of religion in Russia led some Russian Orthodox dioceses abroad to form jurisdictions not affiliated with Moscow. One of these, the Paris-based exarchate, later assumed control of the Nice cathedral. On 20 January 2010, a French Court ruled that the title to the Cathedral should be held by the Russian state.
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.
