During my trip to St. Petersburg I only had a chance to take photos during one evening as I was walking to St. Petersburg University to find a book that a friend of mine wanted me to get there. This was around 7:30 at night, but at this time of the year the city gets as dark as at midnight. During the night the buildings and bridges in the center of the city are beautifully lighted up. I am not sure when they started doing that, but they did not do that when I was living there.
