There are many reasons why the Kremlin is worth a visit. The Moscow Kremlin is a symbol of Russia and one of the greatest architectural complexes in the world. The 36.4 hectare ensemble of the Kremlin has been included in the UNESCO World Heritage List. Its architectural history may be divided into the three periods: the wooden Kremlin (dated back to the 13th century), the Italian Renaissance Kremlin and the modern Kremlin. In addition to all this, every Saturday visitors can witness the сeremonial parade of Horse Guard and Foot Guard of the Presidential Regiment on Cathedral Square. This event takes place at noon but it’s best to arrive earlier because during peak tourist season in the summer there are many visitors from Russia and abroad wishing to see this impressive ceremony.
