The political, scientific, historical, architectural and business centre, the role of Moscow in the country’s turbulent past is aptly reflected through its buildings and monuments. The golden onion domes of the Kremlin's Orthodox churches, stand testimony to the country’s regal past, while Lenin's mausoleum and the massive GUM shopping complex are symbols of Soviet Union’s communist era. For tourists, a major draw of Moscow is the Kremlin. The fortified citadel has stood witness to the many famous and tragic events that changed the course of the nation. Consisting of a multitude of palaces, an ancient tower, former military fortifications, and churches, the Kremlin links the modern day Moscow to its legendary past. The center of Russia’s political life, the Kremlin has been home to Tsars, general secretaries of the Soviet Union and Russian presidents. Lying beneath the walls of the Kremlin, is Moscow’s famous Red Square. Each monument in Red Square has a fascinating legacy. The most famous of these is the unique St Basils Cathedral, which, with its distinct and colourful onion domes is one of the most recognisable buildings in the world. Red Square brings to life the transition of Russia from a tumultuous past to becoming one of the most intriguing capitals of Europe.
