Russia's symbol of victory, the Motherland Calls monument, sits on the hill soaked with blood. It is the site of the most ferocious and important battle of World War II, and thousands of soldiers have been buried in a mass grave underneath the statue. Its sculptor, Evgeny Vuchetich, has managed to embody the heroism of the people, whose popular slogan was "Not a step back", and millions still come to the foot of the monument every year to commemorate the Soviet triumph.
