The Kremlin is the largest fortress in Europe
Not only it’s the largest medieval fortress in Russia, it’s also the biggest active fortress in the whole of Europe. Sure, there has been bigger constructions of this kind, but the Kremlin is the only one that’s still being used.
The Kremlin walls used to be white
The Kremlin walls got their red brick look late in the 19th century, until then the walls had been painted white to preserve the bricks. To see the White Kremlin, look for works by the 18th- or 19th-century painters, like Pyotr Vereshchagin or Alexei Savrasov.
Red Square has nothing to do with the color red
The name comes from the Old Russian word “krasnyi”, meaning beautiful, and is in no way related to the color of buildings, which, as we now know, used to be white until late in the 19th century.
The Kremlin stars used to be eagles
In the days of Tsarist Russia, the four Kremlin towers were topped with two-headed eagles, which had been a Russian coat of arms since the 15th century. In 1935 the Soviet government replaced the eagles, which were melted down and replaced by the five-pointed stars we see today. The fifth star on the Vodovzvodnaya Tower was added later.
The Kremlin towers have names
Of the 20 Kremlin towers only two don’t have proper names, they are called “the first unnamed” and “the second unnamed”. The tallest one is the 80 meter (262 ft) high Troitskaya tower, while the most recognizable is Spasskaya, aka the Kremlin Clock tower.
The Kremlin is densely built up
Behind the 2235 meter-long (7,332ft) Kremlin walls there are 5 squares and 18 buildings, with Spasskaya Tower, Ivan the Great Bell Tower, Dormition Cathedral, Troitskaya Tower and the Terem Palace being the most popular.
The Kremlin survived WWII almost intact
During WWII the Kremlin was elaborately camouflaged to look like a residential building block. The church domes and famous green towers were painted grey and brown respectively, fake doors and windows were painted on the Kremlin walls, and the Red Square was encumbered with wooden constructions. It didn’t suffer much damage, even though Moscow was heavily bombarded in 1941-42.
The Kremlin is in the Guinness Book of Records
Moscow Kremlin is where you can see the world’s largest bell and the world’s largest cannon. The 6.14 metre (20ft) tall Tsar Bell was made in 1735, broke during metal casting and never rang, the Tsar Cannon, weighing 39.312 tonnes, was cast in 1586 and has never been used in a war, but it’s the largest cannon by caliber, according to the Guinness Book of Records.
The Kremlin stars always shine
In their 80 year existence, the illumination of the Kremlin stars has only been turned off only twice First during WWII, when the Kremlin was camouflaged to hide it from bomber aircraft. The second time, they were turned off for a movie. Oscar-winning director Nikita Mikhalkov was shooting a scene for the Barber of Siberia, which is set in pre-revolution Russia.
The Kremlin Clock has a deep secret
The secret of the Kremlin Clock’s accuracy literally lies beneath our feet. The clock is connected to the control clock in Sternberg Astronomical Institute via cable.
