The third Moscow Kremlin is known as the White-stone Kremlin as it was built with a limestone. Grand Duke Dmitry Donskoy, the Kulikovskaya Battle hero, ordered to construct it instead of the easily disposable wooden one. Though the new walls seemed very strong at first, they turned out to be short-lived. The limestone began to crumble in less than a century. The time of our current red-bricked Kremlin came at last. Today the Moscow Kremlin may look authentically Russian, but in fact, Ivan the Great invited Italian architectures to build it according to the newest Rainessance ideas. Most of what the Moscow Kremlin is now was built in 15th and 16th centuries. There were many alterations and reconstructions in the later years, and the new buildings were added constantly to the ensemble, but the core of several cathedrals and palaces remained mostly intact.
The Kremlin remained the main residence for the Tsar up to the end of the 18th century, when Peter the First decided to move the capital to St. Petersburg. By the middle of the 19th century, the Kremlin mostly became a museum. The most beloved tourist attractions were the Tsar- Cannon that is too big to be able to actually fire, and the Tsar-Bell that is too big to actually ring. Needless to say, today tourists love them as much as their predecessors 200 years ago.
