尤里·多尔戈鲁基
Up to the 14th century, the site was known as the 'grad of Moscow'. The word "Kremlin" was first recorded in 1331 (though etymologist Max Vasmer mentions an earlier appearance in 1320). The grad was greatly extended by Prince Yuri Dolgorukiy in 1156, destroyed by the Mongols in 1237 and rebuilt in oak in 1339.
