The great stone platform on the western slope of the natural hill of Tall-e Takht with 80 m. length and 15 m. height has been made up of some 20 layers of huge stone slabs having up to six tons weight. The Throne hill was almost certainly intended to serve as a platform for further impressive construction; and this never-finished project might have partly provided an inspiration for the later, elevated palatial compound at Persepolis.
