The restoration works of Timurid architecture in Samarkand has a long history starting from the period of the Russian colonization. This works dramatically changed the shape of monuments. Soon after Uzbekistan raised as a Presidential Republic, Timurid monument were recognized as a symbol of the country and restoration works were revitalized. In this paper, I focused on the changes of the architecture's shapes by the restoration works, and the various aims of restoration works during Russian colonial period, Soviet period, and after independence. According to detailed research for the restoration process of four main Timurid architectures in Samarkand, the monuments gained the position as historic monuments in the Russian period, and played a propaganda role in the Soviet period. In order to enhance the high quality of historic monuments in the soviet area, researchers made a great effort to study the monuments and realized many extensive restoration works. After the independence, many large-scale restoration works have been undergoing without academic studies and professionals.
