Tonyukuk Monuments are located on the upper side of Tola river in Bayn Tsydo area in Mongolia. The monuments consist of statues 
and two inscription with four faces which were constructed by Bilga Tonyukuk in (732-734 ?) who was the vizier of 11. Kokturk 
Khans. 
Inscriptions of Bilga Tonyukuk and statues in monument are drawn by photogrammetric methods. Photographs are taken with Rollei 
D7 digital camera and Leica R5 optic camera. Additionally, the ground control points are measured by Sokkisha Power Set 2000 
Total Station. Pictran and Photomodeller software are used on photogrammetric restitution and drawing of these statues and 
inscriptions. All restitution results obtained from this study are submitted to the Turkish International Cooperation Agency (TICA).
