A 5th or 6th century AD stone-lined pit, probably used as a hearth, at the site of the proposed converter stations (Bentley).
One feature was recorded dating from the time immediately after the Roman period - a stone-lined hearth at Bentley with charcoal residue that was radiocarbon dated to the 5th or 6th centuries AD. The hearth alone doesn’t indicate a settlement but someone did set a fire at that location, perhaps to cook a meal.
