The Moscow Metro is a subterranean network that facilitates the rapid transit of passengers beneath the city. The circular line acts as a twenty-kilometer ring around the center that runs in a perpetual motion. In just 29 minutes, it orbits the city before repeating the process continually. The unrelenting journey of the circular metro train is without end; not unlike the journey of the people above ground, caught within the repetitive cyclical events that shape life in the city. Starting at the Kremlin, and following the line until he arrived back at his station of origin, Paul Walsh set out to walk Moscow’s circular metro line above ground.
