Welcome to Moscow, and start of your unbelievable holiday and adventure!
You may wish to arrive a few days ahead to explore the amazing capital of Russia. “Kremlin” is not actually a specific place name, but means “fortress”. The most well-known kremlin is of course the one in Moscow, at Red Square. And Red Square is not actually Red because of the red bricks, but because "red" in the old Russian language meant "beautiful". And "Kremlin" meant a castle.
