The brochs are among the best-known ancient monuments in Scotland. However, despite a long and colourful history of research, it is only in the last 20 years that the results of field survey, excavation and radiocarbon dating have begun to flesh out a picture of their evolution and development from around 600 BC to AD 100. This well-illustrated book describes the current state of our knowledge, probes the long-running controversies over their origins and function, and provides an annotated list of the most accessible and best-preserved broch sites. Individual chapters cover: Beginnings; Anatomy of a broch tower; Broch landscapes, broch people; Lords of the north; Lords of the south; Beyond the brochs.
