"The Kremlin is Russia's mythic refuge, a self contained city with a multitude of palaces, armories, and churches, a medieval fortress that links the modern nation to its legendary past in the ancient state of Kievan Rus'. As the dominance of Kiev faded and its empire fragmented under the weight of foreign invasion and 'incessant' strife in the 11th and 12th centuries, regional princes gained power. In 1147, as Kievan Rus was experiencing its final death throes, a chronicler recorded that a feast was held at the hunting lodge of Prince Yuri Dolgorukiy, ruling prince of Rostov and Suzdal. The lodge was perfectly situated atop a hill overlooking the Moskva and Neglina rivers,
prompting its development (in such troubled times) as a fortified town, or Kremlin."     ( http://www. interknowledge.com/russia/moscow02.htm)
