What is the history of a Scottish roch?
The Broch is an Iron Age dry stone structure of a type which is found in Scotland. They are an example of what are more generally classified as Atlantic Roundhouses. The origin of brochs remains disputed. Sixty years ago most archaeologists believed that brochs were built by an influx of broch builders who had been displaced and pushed northward during the Roman invasion of southern England. However, this theory has fallen from favour, since the few radiocarbon dates available point to a much earlier date for the brochs’ floruit. The best-preserved broch, at Mousa, may date from 100BC to 100AD, but other examples are older. The earliest radiocarbon dates obtained have been from remains in Shetland and Caithness. http://en.wikipedia.
