The siege of Singara took place in 360, when the Sasanian Empire, under Shapur II, besieged the town of Singara, held by the Roman Empire. The Sasanians successfully captured the town from the Romans.
The fortifications of SingaraâÂÂincluding its moat, both outer and inner walls, and projecting towersâÂÂclearly reflected the style of late Roman and early Byzantine military architecture, built to withstand well-equipped siege attacks. Roman historian Ammianus Marcellinus describes the Sassanian siege in 360, during which a massive battering ram finally brought down a round tower that had only recently been repaired. This led to the capture of Singara.
The 1st Flavian and 1st Parthian legions which had formed the garrison, as well as the inhabitants of Singara, were sent into captivity in Sasanid Persia.
