Burnt Mound - Possible Explanations

Possible Explanations

The main explanation for burnt mounds is that they were cooking sites. However, there are problems with such explanations, not the least of which is the lack of any direct evidence of cooking. The process undoubtedly works; experiments were carried out in Ireland in the 1950s to show that a joint of meat could be fully cooked in about three to four hours through this method. However, bone is rarely if ever reported from burnt mound sites, which would be unusual for a cooking site. This has been explained as the result of the soils being too acidic for the bone to be preserved, but this is unsatisfactory. It would be rather unlikely that all of the soils relating to burnt mounds were so acidic that no bone survived, particularly as the pH of the soil will vary considerably from site to site. However, there are examples of burnt mounds that have been recorded on neutral or basic soils, without bone being apparent in the burnt mound material, Alternatives that have been suggested include saunas (where the intention is to create steam rather than cook anything), fulling, salt production, leather preparation etc.

The implication found in many accounts of burnt mounds gives the impression that they are found in Ireland and Scotland, but they also are found in Wales and in England. The Welsh examples tend to be upland and rural, as are many of the English ones, but there are also many found in the lowlying English Midlands. Barfield & Hodder's interpretation of burnt mounds as potentially saunas arose from their various excavations of burnt mounds in the Birmingham area, while more recently forty mounds have been discovered in Birmingham. One example is in Moseley Bog where experiments were made in the late 1990s to assess the plausibility of the sauna hypothesis.
