Russia - Saint Petersburg

I received this beautiful postcard in Slavic countries & Rest of the world RR :) I've choosen it myself, so I definitely love it :) It shows the Palace Bridge and view of the Peter and Paul Fortress. I don't know, if that's true, because I've never been to Saint Peterburg, but my friend told me that you should be careful not to stay on the island late in the evening, when the underground is already closed and the bridges are open... Then you have to wait until the morning. I wonder, if that's true :)) Maybe I'll check it myself next year...
