More than 10,000 Russian workers built the first line of the Moscow Metro which opened in 1935 to great fanfare.

The spectacular stations were designed to show the world the power and possibility of Russian strength. Stalin wanted architects to design stations to be 'palaces for the people', with statues and structures built to make people look up and admire the marble walls, high ceilings and grand chandeliers.
