‘Humongous’ fort found in Wales may disprove theory of Celtic-Roman peace

Site in Pembrokeshire suggests area was more militarised than previously thought, says expert who made discovery

A previously unknown Roman fort discovered in Pembrokeshire in Wales overturns assumptions that the area's indigenous Celtic tribe was on peaceful terms with the Roman invaders.

The site, which has excited archaeologists, had been hidden until now beneath an enormous, overgrown field. It explains why the land had been unsuccessful for farming: the farmer kept hitting stone.
