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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
