DAG (Eastern Anatolian Observatory in Turkish), will be built in one of the well-known mountain ridges of Erzurum, Turkey, at latitude of 39 degrees 46'50, longitude of 41 degrees 13'35 and an altitude of 3170 meters. As well as erecting the largest telescope of Turkey, the DAG project aims to establish an observatory complex both small in size and functional enough to give service to all astronomy community. In this paper, the challenge is explained in details: geological and geographical limitations, environmental and meteorological constraints, engineering and structural considerations, energy efficiency and sustainability.
