The word 'Kremlin' means 'fortress inside a city,' and many Russian cities have their own kremlins, but the Moscow Kremlin is the most famous.

The Tsar Cannon, located within the Kremlin grounds, is one of the largest cannons ever made, weighing about 40 tons and cast in 1586, although it was never used in battle.
The Tsar Bell, also within the Kremlin, is the largest bell in the world, weighing 200 tons, but it has never been rung due to a large crack that occurred during casting.
The Kremlin Wall, built in the late 15th century, stretches 2,235 meters (7,332 feet) and includes 20 towers, each with its own unique design and history.
The Spasskaya Tower, one of the most famous towers of the Kremlin, houses the Kremlin clock and serves as the official entrance for presidential and state ceremonies.
The Cathedral of the Dormition, one of the Kremlin's cathedrals, was the site of coronations for Russian tsars and emperors.
