A burnt mound is an archaeological feature consisting of a mound of shattered stones and charcoal, normally with an adjacent hearth and trough. The trough could be rock-cut, wood-lined or clay-lined to ensure it was watertight. Radiocarbon dates vary quite widely, the earliest being late Neolithic, with clusters of dates between 1900 and 1500 BC and 1200–800 BC, with some outliers in the Iron Age. There are also some dates that go into the Early Middle Ages. The technology used at burnt mounds has much greater antiquity and is found from the Palaeolithic onward.[1]
