Аннотация: The article discusses the role and importance of computer modeling in the reconstruction of historical and cultural monuments in Kyrgyzstan's part of the Great Silk Road. Due to a number of objective and subjective causes all monuments of ancient and medieval ages of Kyrgyzstan demonstrate that the abundant historical and cultural heritage has either not been preserved or has been partially or fully renovated thus resulting in its changed appearance. The authors have tried to carry out a 3D reconstruction of Koshoy-Korgon settlement on the basis of former practices aimed at reconstruction of fortification complexes, ancient settlements and historical landscapes. This settlement dates back to the 10th-12th centuries and was the nomadic and administrative center of the At-Bash Valley in the Karakhanid State. The process of Koshoy-Korgon virtual reconstruction was accomplished by stages on the basis of historical and archaeological studies with the help of  such programs as ArchiCAD, Photoshop CS3, Unity3D, Autodesk 3D Max, 3DWorldStudio. 3D virtual reconstruction of disappeared monuments of Northern Kyrgyzstan traditionally considered a region of nomadic cultures  will allow us to take a fresh look at architectural features of monuments along the Great Silk Road and scrutinize social, economical, cultural and political aspects of historical objects. 3D  reconstruction based on comparative analysis will provide for drawing parallels to find out the interpenetration of architectural styles of states along the Great Silk Road in Central Asia.
