The St Petersburg Metro

Because my guide and I had been getting cold she modified the walking tour and we went into the Metro.This amazing system was built in the Soviet era and completed in 1955. Some parts are incredibly deep, I think she said 200 feet underground but all linked by the longest escalators I have ever been on. There always seem to be crowds of people coming and going. Several times Busker musicians played accordion and guitar music. We especially visited several of the incredibly ornate underground stations. Maybe the Metro had been built as Underground nuclear fall-out protection. I should have asked. I was pleased to learn how to get on the Metro (with a token).
