Samarkand is one of the oldest cities in the world - it has more than 2500 years, which is the same age as cities such as Rome or Athens. In ancient times it was one of the main towns located on the route of the ancient Silk Road trade route linking China with Europe and the Middle East. Samarkand experienced the greatest prosperity under the rule of the Timurid dynasty when Timur chose her for the capital of their country. Then Samarkand was one of the most famous in the world centers of culture, science and the arts. In the city are still today many tourist attractions: Registan - the main and most representative tourist attraction of Samarkand is a square surrounded by three monumental mosques, Ulugh Beg mosque of 1,420 years, Shir Dor mosque, Tallya Kari (gold-plated) mosque, Bibi Khanum mosque, mausoleum of Bibi Khanum, Bibi Khanum mosque, Ulugh Beg Observatory - the world’s first astronomical observatory and many others. Mausoleum and mosque of Bibi-Khanum of the fourteenth century was devoted to a Chinese princess, one of the wives of Timur. It is visible from anywhere in Samarkand through the visible 44-foot blue dome. Khanum Bibi mosque, built between 1394-1404 due to the significant size (height of the dome 44 m, width 19 m) began to fall into disrepair soon after the hill and collapsed during an earthquake in 1897, but in 1969, work began renovations that continue to this day.
