Gore, an ancient city within the Firozabad plain, holds historical significance as one of the earliest examples of a geometrically planned city in ancient Iran, earning the distinction of being the first circular city in the region.

The city's roots extend to the Achaemenid period before the Sasanian rule. Flourishing under Achaemenid governance, the circular city of Gōr boasted robust defenses that thwarted any attempts by adversaries to breach its walls. The Firozabad plain, with its strategic geographical position surrounded by towering mountains and flowing rivers, had captivated the interest of ancient Iranian rulers since time immemorial. Access to this area proved challenging due to its rugged terrain.
