The valley floodplain landscape covered by the Gill Mill quarry, almost
130ha, was intensively exploited from about 300 BC at a variety of Iron
Age settlements. The largest of these remained in occupation into the
early 3rd century AD, but meanwhile a large nucleated settlement grew up
around a road junction roughly 1km distant to the NW. This became the
sole focus of occupation, covering an area of about 10ha. Featuring
multiple ditched enclosures, some in very regular layouts associated
with one of the roads, the settlement contained relatively few
identified buildings and appears to have had a specialized economic role
related to systematic cattle management, illuminated in part by large
finds and environmental assemblages. It may have been an integral
component of a wider estate holding and perhaps had an administrative
focus (including a shrine) at its unexcavated center. It is notable that
occupation of the site had almost entirely ceased by about AD 370.
