A few of St Petersburg's metro stations are serious work of art, and they also include art. Ride along the red line to find them. One of those stations is Avtovo. The columns are glass coated, in case you are wondering. Not in this pic: an impressive mosaic of the Leningrad blockade during world war II.
Couple of notes regarding St Petersburg metro system: efficient mean of transportation and trains come every minute. Yes, every *One* minute. So use it, and remember, no need to run to a train!
All stations have English signs and it's easy to get by. It almost feels like cheating.
