The megalithic monuments of Carnac, Brittany, in the Département of the Morbihan, are amongst the most farnous in France. indeed in the world. This region has not only the densest conccntration of such sites in Europe but also retained its importance as a centre of monument-building from the late 5th to the :jrd millennium FK:, giving it a unique significance in the study of Neolithic landscapes (Sherratt 1990; 1998). Its menhirs, stone alignments, and megalithic tombs have attracted the attention of scholars since the 18th century, and there is thus an unusually full record, both written and pictorial, of the nature of these monuments as they were perceived over 300 years.
