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 Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
