This is one of the main attractions of the capital.
5. In 1889-1893 there was constructed the building which is known as GUM – top
shopping streets, designed by A. Pomerantsev.
6. After the 1917 revolution name of the area associated with the victory of the “red”
and the Red Square and the Kremlin have become symbols of the revolution. After
the death of Lenin in 1924 was built a mausoleum. First it was wooden and later it
became marble. These years the monument to Minin and Pozharsky was postponed.
7. In 1990 the complex of the Moscow Kremlin and Red Square were included in the
list of UNESCO World Cultural Heritage. Red Square is open for tourists around the
clock. In some cases it may be closed during the preparation for the big holidays,
such as Victory Parade.
8. In recent years near the GUM there is a rink. Its size reaches 3 million square
meters and it holds up to 500 people. And of course many people prefer to celebrate
the main holiday – the New Year – exactly on the Red Square
