The political, scientific, historical, architectural and business centre of Russia, Moscow displays the country's contrasts at their most extreme. The ancient and modern exist side by side in this city of 10 million. Catch a metro from one of the ornate stations to see Red Square, the Kremlin, the nine domes of St Basil's Cathedral, Lenin's Mausoleum, the KGB Museum and other symbols of Moscow's great and terrible past, then lighten up and go shopping in Boulevard Ring, or people-watch in Pushkin Square.
