This monograph concentrates on early Irish medieval dwellings and settlements, AD 400-1100, and is directly based on a report compiled and written in the main over the course of 2009 and 2010, largely based on evidence available up to that time. Drawing on both published and unpublished material, it sets out an interpretive, analytical text and a gazetteer of some 241 key early medieval settlements revealed through archaeological excavations. The report also focuses on such themes as houses and buildings, the organisation of settlement enclosures, agricultural activity and crafts and industry; it arguably represents the first compilation, analysis and discussion of early medieval settlement archaeology in Ireland.
