Qaṣr-i Abu Naṣr (Persian: قصر ابونصر, lit. Abu-Naṣr Palace), Qasre Abunasr, or Takht-e Sulayman (Persian: تخت سلیمان, lit. Throne of Solomon) is the site of an ancient settlement situated in city of Shiraz in the Fars province of Iran. According to archaeological studies the fortress was built during the Parthian period, and was an important and strategic location in the Sassanid Empire. Archaeologists have found various artifacts and coins belonging to various historical periods, such as the Achaemenid, Seleucid Empire, Parthian and Sassanid. This site is recorded in an Iranian historical list from 1932 as "Takht e Sulayman" ( Throne of Solomon). When Muslims invaded Iran, and conquered it, they called this palace "Father of Victory" (Qaṣr-i-Abu Naṣr)[1]
