The green hilltop of Fin Cop seems peaceful and unthreatening to a modern spectator, but beneath the ground is a mass grave dating back to the Iron Age. This raised many questions when the fort was uncovered and showed evidence that parts of it had been built quickly in response to a threat to the settlement.
Hillforts were originally assumed to have been built for warfare, but without much evidence of actual conflict many were instead viewed as a show of wealth and power.
The findings from Fin Cop give one of the only examples of warfare in Iron Age Britain, but other settlements have been discovered which show similar evidence. This is challenging our ideas of Iron Age warfare and defence once again.
