The Moscow Kremlin (Russian: Московский Кремль Moskovskiy Kreml) usually referred to as simply The Kremlin, is a historic fortified complex at the heart of Moscow, overlooking the Moskva River (to the south), Saint Basil’s Cathedral and Red Square (to the east) and the Alexander Garden (to the west). It is the best known of kremlins (Russian citadels) and includes four palaces, four cathedrals, and the enclosing Kremlin Wall with Kremlin towers. The complex serves as the official residence of the President of Russia.
The site has been continuously inhabited since the 2nd millennium BC, and originates from a Vyatich fortified structure on Borovitsky Hill where the Neglinnaya River flowed into the Moskva River. The Slavs occupied the south-western portion of the hill as early as the 11th century, as testifies a metropolitan seal from the 1090s, which was unearthed by Soviet archaeologists on the spot.
Until the 14th century, the site was known as the grad of Moscow. The word “kremlin” was first recorded in 1331 and its etymology is disputed (see Vasmer online). The “grad” was greatly extended by Prince Yuri Dolgoruky in 1156, destroyed by the Mongols in 1237 and rebuilt in oak in 1339.
The existing Kremlin walls and towers were built by Italian masters over the years 1485 to 1495. The irregular triangle of the Kremlin wall encloses an area of 275,000 square meters (68 acres). Its overall length is 2235 meters (2444 yards), but the height ranges from 5 to 19 metres, depending on the terrain. The wall’s thickness is between 3.5 and 6.5 meters.
