This article considers the evidence for Early Neolithic long barrow construction on the West Mendip plateau, Somerset. It highlights the difficulties in assigning long mounds a classification on surface evidence alone and discusses a range of earthworks which have been confused with long barrows. Eight possible long barrows are identified and their individual and group characteristics are explored and compared with national trends. Gaps in the local distribution of these monuments are assessed and it is suggested that areas of absence might have been occupied by woodland during the Neolithic. The relationship between long barrows and later round barrows is also considered.
