Deep green and bright yellow domes of the Russian Orthodox Cathedral treat visitors to a slice of Russia in the Côte d'Azur. Although it’s a lesser-known gem in Nice, it’s the largest Eastern Orthodox Cathedral in Western Europe – so it’s pretty important and well worth adding to your itinerary. If you’re wondering why it’s here, that’s because since the mid-19th century, wealthy Russians have been swapping their snowboots for sunglasses to get some winter sun in Nice. The cathedral was built to give this growing community its own place of worship. Look up at the swirling onion domes, mosaics and architectural details – or step inside. It’ll leave you speechless.
