The siege of Pirisabora took place when the Roman Emperor Julian besieged the fortified city of Pirisabora under Mamersides in April 363. After two days of fierce fighting, the Sasanians and the citizens abandoned the circuit walls and took up a defensive position in the acropolis. After some failed attempts, the Romans began to construct a siege tower, after which Mamersides reached a compromise with Julian to hand over the fort in exchange for a safe withdrawal. Julian subsequently pillaged and burned the abandoned city.
