Located in the center of Nice, the Russian Orthodox Cathedral is a must visit during your stay in Nice. The architecture is very stand out from the rest of the buildings in the city. It's a quiet area surrounded by tall trees. While you are walking down the busy street and started to wonder if this is the right direction, and here you are - a beautiful building pops right in front of you.
*in order to go inside, you should wear clothes that cover shoulders, etc. they do offer some scarfs at the entrance.
