Here are a couple of photos of Red Square and the Kremlin, day and night, from my Moscow trip a couple of weeks ago. Saint Basil’s Cathedral is in the background. It was about 60 degrees warmer than last time I was there — which is to say it was a perfect 70-something rather than 20 degrees below freezing!
It’s a great run to do laps around the perimeter of the Kremlin (it’s perimeter is 1.5 miles).
