In 1935, the first part of Moscow's metro, or Moskovsky metropoliten, opened to the public. For nearly 80 years, the system has been ferrying visitors and locals around the Russian capital.

Riding the metro is Moscow isn't just a quick way to get around a city known for long, cold winters. It's like a trip back in time.
Construction of the system was started in the 1930s, under Stalin.

The stations double as air raid shelters, and most are deep underground.
