The ancient citadel of Arg-é Bam has a history dating back around 2,000 years ago, to the Parthian Empire (248 BC–224 AD), but most buildings were built during the Safavid dynasty. The city was largely abandoned due to an Afghan invasion in 1722. Subsequently, after the city had gradually been re-settled, it was abandoned a second time due to an attack by invaders from Shiraz. It was also used for a time as an army barracks.
