Firuzabad (Persian: فيروزآباد) is a city in the Central District of Firuzabad County, Fars province, Iran, serving as capital of both the county and the district. Firuzabad is south of Shiraz. The city is surrounded by a mud wall and ditch.
The original ancient city of Gor, dating back to the Achaemenid period, was destroyed by Alexander the Great. Centuries later, Ardashir I, the founder of the Sassanid Empire, revived the city before it was ransacked during the Arab Muslim invasion of the seventh century. It was again revived by the Buyids under Fanna Khusraw, but was eventually abandoned in the Qajar era and was replaced by a nearby town, which is now Firuzabad. Its only surviving structure is the central core, an ancient tower.
