EAA 168: Small Communities: Life in the Cam Valley in the Neolithic, Late Iron Age and Early Anglo-Saxon Periods : Excavations at Dernford Farm, Sawston Paperback / softback

Excavation of a site on river gravels in the Cam/Granta valley, by Archaeological Solutions Ltd, took place in advance of gravel extraction and construction of a reservoir.

The excavation revealed five phases of archaeological activity, beginning in the Neolithic period with evidence for episodic or seasonal occupation and burial.

After a gap of several centuries, there were three phases of Middle Iron Age to early Roman activity representing the continuous development of the same system of enclosures focussed on a central trackway.

Domestic occupation was also evident in the form of partial ring gullies.

During the Conquest period there was probably a landing site for boats operating on the former river channel evident at the site.

Economic activity during these phases represents a mixed, surplus-generating economy and it is possible that river traffic played an important role in the trade of the agricultural surplus.

Limited finds of later Roman artefacts indicate a continued Romano-British presence in the vicinity.

The final phase of occupationis a small rural Anglo-Saxon settlement comprising seven sunken-featured buildings and associated pits.

Environmental and soil micromorphological analysis from this phase has provided important information about the internal arrangement of SFBs and the processes associated with development of their fills.
